Best Slab Rollers for Pottery: North Star, Bailey, Brent and Shimpo Compared

A slab roller presses clay between a roller and a canvas-covered table to make flat sheets of even thickness, far faster than a rolling pin. The best slab roller for a home studio depends on two numbers: the roller width, which sets how wide a slab you can make, and the table or footprint, which sets how much room you need. Below we compare eight options. They run from North Star, Brent and Shimpo floor and tabletop machines down to rolling guide sets that cost a few dollars.

This guide is research-based. We compared North Star Equipment’s product and warranty pages, Bailey Pottery’s product page, Shimpo’s slab roller page, and dealer listings from Sheffield Pottery and Clay-King. We did not roll clay on these machines ourselves. Specs checked October 2026.

Slab roller comparison table

What does a slab roller do?

A slab roller flattens a lump of clay into a sheet of even thickness. You lay the clay on canvas, set the gap, and crank the handle so the roller (or a pair of rollers) presses the clay down to that gap as it passes through. In ceramics, those flat slabs become mug wraps, boxes, tiles, plates, platters, vases built from panels and wall pieces.

Why would you want one? Three reasons stand out. First, speed: a ceramic slab roller makes in one or two passes a slab that takes many minutes with a rolling pin. Second, consistency: every slab comes out the same thickness edge to edge, so pieces dry and shrink more evenly and parts fit together. Third, effort: cranking a geared or cable-drive machine is far easier on the wrists and shoulders than rolling stiff clay by hand. Slab rollers also compress the clay as it passes through, and many potters flip and roll a slab in two directions to help limit warping.

If you roll a few small slabs a month, guide sticks and a rolling pin do the same job for a few dollars; our slab roller vs rolling pin comparison covers where the line is.

North Star 24 in Standard Slab Roller: best overall

North Star (sometimes written Northstar) is a US maker whose slab rollers turn up at every pottery dealer we checked, and its 24 in Standard package is the one we would point most home potters to first. The 24 in roller is wide enough for mug wraps, boxes, tiles and medium platters, and the Standard series adjusts thickness from 0 to 2 3/4 in.

North Star’s design uses a bottom roll turned by the handle and a geared top roll that adjusts up and down for infinitely variable thickness, rather than fixed shims. Sheffield Pottery describes a cast aluminum body and rolls with steel gears and no chains or cables, which means fewer parts to stretch or adjust. The package includes the roller, a 14 gauge steel table, canvas and a wagon wheel handle. Sheffield lists the table as 4 ft with a moisture-resistant Medex top and melamine surface.

The warranty is a strong point. North Star’s policy covers its slab rollers for the life of the machine. Standard series rollers used in commercial or academic settings get 24 months instead. It ships in three cartons listed at 35, 50 and 35 lb, so plan on two people for setup.

• Roller width: 24 in
• Thickness: 0 to 2 3/4 in, infinitely variable
• Drive: gear driven, no chains or cables
• Table: 4 ft table included (14 gauge steel per North Star; Medex top per Sheffield)
• Shipping weight: three cartons, 35, 50 and 35 lb
• Warranty: lifetime for personal use; 24 months for commercial or academic use
• Price band: typically $1,650 to $1,750 in October 2026; check the live price

Who should skip it: Potters who roll a slab or two a week and have no room for a 4 ft table.

North Star 30 in Slab Boss: best for wider slabs

The Slab Boss is North Star’s 30 in Standard series machine. North Star lists the same 0 to 2 3/4 in thickness range as the 24 in model, with a 14 gauge steel table, canvas and wagon wheel handle in the package. Sheffield lists a 4 ft table and notes that the roller has no chains, cables or cast iron gears and can roll in either direction.

Six more inches of roller width matters if you make large platters, wide tiles, big slab boxes or wall pieces. Rolling in either direction also saves time, because you do not have to carry the slab back to the start for a second pass.

The price gap to the 24 in model is small at the dealers we checked, so if your space allows the wider frame, it is worth considering. It ships in four cartons listed at 40, 53, 35 and 10 lb. The same North Star warranty terms apply as on the 24 in Standard.

• Roller width: 30 in
• Thickness: 0 to 2 3/4 in
• Drive: gears, no chains or cables; rolls in either direction
• Table: 4 ft table included (Sheffield)
• Shipping weight: four cartons, 40, 53, 35 and 10 lb
• Warranty: lifetime for personal use; 24 months for commercial or academic use
• Price band: typically $1,800 to $1,900 in October 2026; check the live price

Who should skip it: Hand-builders who make mugs and small boxes, which a 24 in or smaller roller handles.

North Star 36 in Super Slab Roller: best for classrooms and heavy use

The Super series is North Star’s heavy-duty line. North Star lists the 36 in Super package (item 1050) with a 36 in roller, 0 to 2 1/4 in thickness, a 6 ft work table with removable Medex tops, a wagon wheel handle and canvas. A 4.33:1 reduction gear sits between the handle and the roller, so each turn takes less effort, which helps with stiff clay and long sessions.

North Star gives the Super series a lifetime warranty for the original purchaser, excluding tabletops, canvas and abuse. Note the thickness range: at 2 1/4 in maximum, the Super goes slightly less thick than the Standard series, which hardly matters for pottery slabs.

This is a machine for a dedicated studio, a classroom or a potter who rolls slabs every day. It ships in four cartons listed at 86, 67, 60 and 10 lb. North Star also sells 24 in and 30 in Super packages if you want the gearing without the full width.

• Roller width: 36 in
• Thickness: 0 to 2 1/4 in
• Gearing: 4.33:1 reduction between wagon wheel and roller
• Table: 6 ft work table with removable Medex tops
• Shipping weight: four cartons, 86, 67, 60 and 10 lb
• Warranty: lifetime for the original purchaser (excludes tabletops and canvas)
• Price band: typically $3,700 to $3,850 in October 2026; check the live price

Who should skip it: Any home potter without a dedicated studio room or garage bay.

Brent SR-14 Slab Roller: best Brent slab roller

The Brent SR-14 uses a patented cable drive with opposing rollers, a different design from North Star’s single top roller. Clay-King lists a 14 in roller width, slabs up to 1 3/4 in thick and up to 14 x 36 in, and two versions: one with free-standing legs and one without legs for mounting on your own table. With legs, the assembled size is 27 x 52 in and 40 in high.

Clay-King says it comes with two 1/4 in shims with canvas, a 1/8 in plain shim, canvas and a circular handle, and carries a 1-year maker warranty.

The catch is width for money. At 14 in, it is narrower than every North Star here yet costs more than the 24 in Standard at the dealer we checked. Cables also need checking for tension and wear over the years. Pick it if you want the Brent brand, need the compact footprint, or are matching equipment in a Brent classroom.

• Roller width: 14 in
• Thickness: up to 1 3/4 in
• Max slab: 14 x 36 in
• Drive: cable drive with opposing rollers
• Footprint: 27 x 52 x 40 in with legs; tabletop version available
• Warranty: 1 year (Clay-King listing)
• Price band: typically $2,650 to $3,450 at US dealers in October 2026, depending on legs; check the live price

Who should skip it: Anyone who wants slabs wider than 14 in or the most roller for the money.

Shimpo SRM-1624 Mini: best portable Shimpo slab roller

Shimpo lists the SRM-1624 Mini Slab Roller with a 16 x 24 in table, a thickness indicator for synchronized fine adjustment, a locking two-roller lever system and a compact, portable design. Sheffield Pottery adds a 31 lb unit weight, slabs up to 1 in thick, and a 2-year warranty.

At 31 lb, this is a mini slab roller you can lift onto a bench, use, and store on a shelf. That makes it a practical choice for an apartment, a shared kitchen table or a small garage corner. A 1 in maximum is more than enough for most functional slab work.

One honesty note: the Amazon listing our product box links to does not name the model clearly. The listing appears to be the SRM-1624, but we could not confirm that, so check the model number on the listing before you buy. Shimpo also makes a floor model, the SR-3050, which it lists with a 30 x 50 in table and slabs up to 3 in thick. We did not find a US price for it.

• Table: 16 x 24 in (Shimpo)
• Thickness: up to 1 in (Sheffield); thickness indicator
• Weight: 31 lb (37.5 lb shipping)
• Drive: manual crank, locking two-roller lever system
• Warranty: 2 years (Sheffield listing)
• Price band: typically $800 to $890 in October 2026; check the live price

Who should skip it: Potters who want slabs wider than 16 in or a machine that stays set up on its own table.

Bailey Mini Might II: best tabletop slab roller on a budget

The Bailey slab roller most home potters look at is the Mini Might II, a tabletop machine that sits on your own table. Bailey says the 16 in model makes slabs up to 16 x 18 in, with thickness from 1/8 to 3/4 in in 1/8 in steps. You set thickness by adding or removing masonite shims rather than turning a dial.

The package includes six 16 x 18 in masonite shims, each 1/8 in thick, and one canvas. Bailey says there is no need to clamp it down, because rubber feet hold it in place, and side guides keep the shims centered as they pass through. A 15 in crank handle gives leverage.

Shim-based thickness is slower to change than a geared top roller, and 18 in is the slab length limit. In return, the price is a fraction of a floor machine. One caution: the Amazon listing does not make the size clear, and Bailey sells more than one Mini Might size, so confirm you are getting the 16 in model these specs describe.

• Slab size: up to 16 x 18 in
• Thickness: 1/8 to 3/4 in in 1/8 in steps, set with shims
• Included: six 1/8 in masonite shims, one canvas
• Crank: 15 in handle
• Mounting: rubber feet, no clamps needed
• Warranty: not published on the product page
• Price band: typically $430 to $470 in October 2026; check the live price

Who should skip it: Anyone who needs slabs longer than 18 in or thicker than 3/4 in.

Rolling guide sticks and rolling pin: best no-machine kit

Before buying a machine, many hand-builders roll slabs with a rolling pin and a pair of guide sticks. The sticks sit on each side of the clay, the pin rides on top of them, and the slab ends up exactly as thick as the sticks. This unbranded 11-piece set includes a wooden rolling pin and guide sticks in five thicknesses from 3 to 12 mm, according to the listing.

That 3 to 12 mm range (about 1/8 to 1/2 in) covers almost all functional slab work. The set has no maker spec sheet, so treat the listing as your only data and check the stick lengths in the photos against the slabs you want.

Hand-rolling takes more effort than a machine, and very large slabs are hard to roll evenly by hand. For learning slab building, though, it costs a tiny fraction of any roller here. Our slab roller vs rolling pin comparison covers when it is time to upgrade.

• Contents: wooden rolling pin plus guide sticks (11 pieces in total)
• Thicknesses: five, from 3 to 12 mm (listing)
• Maker data: unbranded; no spec sheet
• Price band: typically under $25 in October 2026; check the live price

Who should skip it: Potters who roll many large slabs each week.

Maitys slab roller strips: cheapest guides

If you already own a rolling pin, the Maitys set gives you just the guides: six wooden strips in three thicknesses (two of each), each 15.8 in long, according to the listing. Pairs of strips set the slab thickness, and the 15.8 in length suits slabs for mugs, small boxes and tiles.

The listing does not give the exact thicknesses in a maker spec sheet, so check the product photos and measure the strips when they arrive. Wooden strips can swell if left wet, so wipe them and let them dry flat after each use.

Guide strips also help with a slab roller. Some potters use them to finish a slab by hand, or to roll a quick test slab without setting up the machine. Pair them with a canvas or cloth to stop the clay sticking to your table.

• Contents: 6 wooden guide strips
• Thicknesses: three (listing)
• Length: 15.8 in (listing)
• Maker data: listing only; no spec sheet
• Price band: typically under $20 in October 2026; check the live price

Who should skip it: Beginners with no rolling pin, who should buy the full guide set instead.

Slab roller brands compared: North Star vs Brent vs Shimpo vs Bailey

Four brands cover most slab rollers sold by US pottery dealers, and each takes a different approach. This summary uses the same maker and dealer data as the reviews above.

North Star is the widest range and the strongest published warranty, and its gear drive has no cables to adjust. It is the default pick for a floor machine. Brent presses from both sides with opposing rollers and has a compact footprint, but gives the least roller width for the money at the dealer we checked. Shimpo is the portable choice: the 31 lb Mini stores on a shelf and has a thickness indicator. Bailey is the budget tabletop choice, trading speed of adjustment (shims) for a much lower price. If you share a classroom or community studio, matching the brand already in use makes canvas and parts easier to source.

How to choose a slab roller for clay

Start with the slabs you want to make, then check whether you have room for the machine that makes them.

Roller width and slab size

Roller width sets slab width. To wrap a cylinder, the slab must be as long as the cylinder’s circumference: a 3.5 in wide mug needs about 11 in of slab (3.5 x 3.14). Most rollers can roll a slab longer than their width, so a 14 or 16 in roller handles mug wraps easily. Go to 24 in for platters and large boxes, and 30 to 36 in for big wall pieces and classroom volume.

Table space and floor space

Floor rollers need the length of their table plus room at each end to pull the canvas through. North Star’s Standard packages ship with a 4 ft table and the Super with a 6 ft table. Brent lists the SR-14 with legs at 27 x 52 in. Tabletop machines such as the Bailey Mini Might II and the Shimpo SRM-1624 need a sturdy table and clear space for the slab to come out the far side. Measure before you order, and see our home pottery studio setup guide for layout ideas.

Drive type and thickness setting

North Star uses a geared top roller with infinitely variable thickness. Brent uses a cable drive with opposing rollers and shims. The Bailey Mini Might II sets thickness with stacked shims, and the Shimpo Mini uses a lever system with a thickness indicator. Geared and dial-set machines are faster to change; shim systems are cheaper and very repeatable.

Tabletop slab roller or floor model

A tabletop or mini slab roller suits small spaces and occasional use. A floor model suits anyone rolling slabs every session. Before you buy a table top slab roller, check that your table is solid enough to take the cranking force without rocking; a tabletop clay slab roller needs clear table length on both sides for the slab and canvas to pass through. North Star also sells tabletop machines, the PortaRoller (18 in), Polaris CT-500 (24 in) and Sirius Star 30 (30 in), but its tabletop page does not show prices, so we did not rank them.

Buying a used slab roller for sale

Used slab rollers come up often when schools and studios upgrade. Before buying one, check that the rollers are smooth and not dented, that the gears or cables turn without slipping or fraying, that the canvas and handle are included, and that the table is flat. Ask for the model number so you can find parts. North Star’s Super warranty covers the original purchaser, so a used machine may not carry it.

Shipping and freight for heavy slab rollers

New slab rollers for sale are sold mainly through pottery dealers and school suppliers, and shipping is a real part of the cost. How a machine travels depends on the maker:

• North Star: Nasco's listing for the Standard package says it ships UPS directly from the factory in three cartons. The carton weights differ by source: The Ceramic Shop lists 35, 50 and 35 lb (120 lb combined), while Nasco lists 35, 40 and 60 lb. The Ceramic Shop says its shipping rate applies only to the contiguous United States.
• Brent SR-14: Clay-King says it ships from the manufacturer by freight carrier with a 6 to 8 week lead time, and that extra fees may apply to reach some addresses; Clay-King says it will contact you before shipping if that happens.
• Shimpo SRM-1624 Mini: Sheffield lists a 37.5 lb shipping weight, small enough for regular parcel delivery.

Before you order, ask the dealer for the delivered price to your address, whether residential delivery or a liftgate costs extra on freight items, and how long the lead time is. Inspect every carton for damage before you sign for it, and note any damage on the delivery receipt.

Assembly on arrival

Floor slab rollers arrive as a kit, not a finished machine. Nasco's listing for the North Star Standard package says "some assembly required", and North Star posts assembly and operation instructions on its own website. Expect to bolt the roller to the table frame, fit the handle and lay out the canvas. Brent sells the SR-14 with a leg set or without legs for mounting on your own table, and the Bailey Mini Might II needs no clamping at all because rubber feet hold it in place.

A few habits make setup easier: open the cartons where the machine will live, check the parts against the packing list before you start, have a second person for lifting the frame and roller, and make sure the table stands level so slabs come out even. Read the whole manual first, and keep fingers clear of the rollers when you test the crank.

What is a vertical slab roller?

A vertical slab roller stands upright and draws clay down between two panels or rollers, so it uses wall space instead of table length. The idea is real: a 2012 US patent (US 8,323,552) describes a vertical slab roller worked by a hand crank. None of the four brands we compared lists a current vertical model, though, and we found no maker spec sheet for one, so we do not recommend one here. If you find one used, ask for the maker, parts availability and the maximum slab size before you pay.

Canvas, texture and clay

Canvas stops clay from sticking and gives slabs a light texture. You can also roll texture mats, lace or texture rollers into the surface. A clay with some grog resists warping in slab work; see our pottery clay guide.
