Standard Cutting Board Dimensions

by Wonderful Household Editorial Team

Standard cutting board dimensions run from roughly 25 × 18 cm for a paring board to roughly 70 × 45 cm for a carving board, with thickness between about 10 mm and 75 mm. Those figures are common industry ranges, not a specification: exact dimensions and tolerances are confirmed per SKU at quotation.

No single figure is standard for every buyer, because four constraints set it: the station sets the footprint, the wash method sets the thickness, the packing format sets the carton, and the container sets what can be shipped at a workable freight cost. A buyer who arrives with a footprint, a thickness and a packing format is placing an order.

The page runs in the order buyers work:

• How thick should a cutting board be
• What size cutting board for a commercial kitchen
• Custom cutting board sizes
• Cutting board size and carton dimensions
• How do I specify cutting board sizes for an order? - read this first if you are ready to quote; the answer is in the FAQ at the end

The chart below is the one to quote from. It is grouped by board class, because buyers order by what the board has to do rather than by what a catalogue calls it.

Board class	Length (cm)	Width (cm)	Length (in)	Width (in)
Paring / prep board	25–35	18–25	10–14	7–10
Standard kitchen prep	35–45	25–30	14–18	10–12
Large home / reversible	45–55	30–38	18–22	12–15
Commercial prep station	45–60	30–40	18–24	12–16
Carving / presentation	50–70	35–45	20–28	14–18
Serving and charcuterie	30–45	20–30	12–18	8–12

Two notes on reading it. The cm and inch columns are the same dimensions written twice, not two ranges - the chart gives both because purchase orders arrive in both, and a specification naming one unit without the other is the most common source of a size dispute. The ranges describe the class, not our output: our per-SKU figures sit in the specification sheet for each item and are confirmed per SKU at quotation. Where a buyer needs a number to plan shelf height or carton volume, that sheet is the document to request.

The same chart answers both spellings - cutting board sizes and chopping board sizes describe the same classes, and suppliers use the two terms interchangeably in quotations.

How thick should a cutting board be

Thickness follows the work, not the footprint. A board that only carries a finished loaf and a board that is struck with a cleaver can share a length and width and sit at opposite ends of the thickness range.

Thickness band	Typical use	Millimetres	Inches
Light	Serving, charcuterie, presentation, front-of-house	10–15	0.4–0.6
Standard prep	General kitchen prep, home and light commercial	18–25	0.7–1.0
Heavy prep	Commercial kitchens, high-volume stations	30–45	1.2–1.8
Butcher block / carving	Cleaver work, display carving, countertop showpieces	45–75	1.8–3.0

The thickness chart and the size chart are deliberately separate: a single table mixing footprint and thickness becomes unreadable where a buyer needs it.

As with the size chart, these bands describe the class, not our output: per-SKU thickness sits in the specification sheet and is confirmed at quotation.

Three things decide where a given order lands on the thickness chart.

The wash method. A board that goes through a commercial wash cycle sits in a different band from one wiped by hand, because it has to keep its geometry through the wash. Fix the wash method before the thickness, not after.

The material line. Available thickness is partly a function of how the material is supplied. Wood and bamboo boards are built up from planks, wood fiber boards are produced as a panel, and melamine boards are moulded, so the workable thickness range differs across the three lines and is confirmed per line and per SKU at quotation. A thickness taken from a chart for one line is not automatically available in another.

The weight it creates. Thickness is the cheapest lever on unit weight and the most expensive one to discover late. A thicker board raises weight per unit, which changes carton grade, gross weight per carton and the freight you are quoted. Where the specification is open, fix thickness against the freight budget.

One habit: ask for nominal thickness and its tolerance as two separate figures. A nominal thickness without a tolerance is not a purchasable specification - two suppliers quoting it can be producing different boards.

What size cutting board for a commercial kitchen

Commercial sizing is set by the station, the wash cycle and the colour-coding system, in that order. A board chosen from a retail size chart will fit one of the three and miss the other two.

Station footprint. Measure the counter depth you work at, not the full depth of the unit: a board that fills the counter leaves no clearance behind it for items set down during prep. Board width is the dimension that decides whether the line works, and it should come from a measured drawing or a tape measure on site.

The wash cycle. The board has to fit what it is washed in - a pass-through, a rack, or a dedicated board washer. A board that suits the station and not the wash equipment will be washed by hand and leave the rotation early. Where racks are used, quote the rack footprint with the station dimension.

The colour system. Colour-coded sets assign each colour to a category of food, which makes a commercial order a matrix rather than a list: colours across one axis, sizes down the other. Buyers who send only size and total quantity reopen the specification once colours are assigned.

Industry practice, shown for reference: colour-coded boards used in commercial kitchens are commonly made of high-density polyethylene. This image illustrates the colour-system convention; our wood and wood-fiber boards are specified separately.

For wholesale cutting board sizes, the consequence is that a commercial range is ordered as a set, not as single items. Ask for the set matrix - which sizes are produced in which colours - because a colour available in one size and not another will not appear in a per-item price list.

Two further checks belong in the brief. The storage rack sets the maximum thickness a site can hold, so a thickness right for the work and wrong for the rack fails on delivery. Corner treatment matters where boards are stacked wet, because square and radiused corners stack differently.

Custom cutting board sizes

Yes - custom footprints and thicknesses are produced to a buyer's own dimensions, and the work starts from what the buyer sends. A custom size is not a special favour negotiated at the end of a quotation; it is an input to it.

Four items are mandatory before a custom size can be quoted or sampled:

1. Length - the longest edge of the finished board.
2. Width - the second edge, measured on the same face.
3. Thickness - nominal, with the tolerance you will accept.
4. Unit - cm or inch, stated explicitly rather than implied.

The fourth item causes more trouble than the other three combined. "18" means 18 cm to one buyer and 18 inches to another, and an order that leaves the unit to context is produced to whichever reading the maker assumes. State the unit in words and give the converted figure alongside it.

Beyond the four, these details change what is produced and should be settled before the sample is made rather than after:

• Tolerance on length, width and thickness, as an acceptable range rather than a single figure.
• Corner treatment - square, radiused or with a cut-out, since the profile affects packing and stacking.
• Handle or grip - position and type, through-hole or routed, because the position is fixed before the pattern is cut.
• Edge profile - square, chamfered or rounded, which also affects how the board sits on a counter.
• Face pattern direction - for decorated or directional patterns, specify the direction relative to the length or width.
• Packing format - individual shrink, inner box, divider or bulk, because packing is what produces the carton dimensions in the next section.

Two commercial points belong in the same conversation. Custom sizes normally carry a minimum per size, since each footprint is set up separately, so an order concentrated on fewer sizes is cheaper per unit than one spread across many. Where a custom footprint needs a new mould, the mould is built before sampling, which changes the sampling sequence rather than the price alone.

The action this section exists for: send the four mandatory items plus whichever details are already decided, and the answer comes back as a specification with a per-SKU confirmation. A photograph of an existing board is workable too, provided a measured edge is included - a photograph gives proportion, not dimension.

Cutting board size and carton dimensions

Carton dimensions are derived from board dimensions, and the derivation runs in one direction: the board's longest edge sets the carton's internal length, the second edge sets the internal width, and the stack of boards plus dividers sets the internal height. Nothing in the carton is chosen independently of the board.

The chain to ask for, in order:

1. Board footprint and thickness - the finished item as specified.
2. Pack clearance - the allowance per side for shrink film, divider, corner protection or inner box. Buyers leave it out, and it is why two suppliers can quote the same board and ship different cartons.
3. Carton internal dimensions - footprint plus clearance, stack plus dividers.
4. Carton external dimensions - internal plus board grade thickness on all six faces.
5. Units per carton and gross weight - both are needed; either alone will not produce a freight estimate.
6. Pallet pattern - cartons per layer and layers per pallet.
7. Container load - computed from the pallet or carton figures, not estimated by eye.

Two calculations are worth doing before you accept a quotation, because they expose a carton chosen for the product rather than for the shipment.

Cartons per pallet layer is the number of cartons that fit in one direction multiplied by the number that fit in the other, both rounded down. Because both round down, a small increase in carton footprint can remove a whole column from the layer, and the loss is larger than the change in board size suggests. It is a common reason a slightly larger board ships at a noticeably higher freight cost per unit.

Cartons per container is usable container volume divided by the carton's external volume, then checked against the weight limit and the stack height the cartons tolerate. Volume is seldom the binding constraint: a dense board packed tight reaches the weight limit first, and a thick board in a tall carton runs into stack height before either.

Four data points let a buyer compute freight before ordering, and all four belong in the quotation: carton internal dimensions, carton external dimensions, units per carton with gross weight, and the pallet pattern. A supplier quoting a board size without the carton figures is quoting a product, not a shipment.

One clarification belongs in writing. When a quotation lists dimensions, confirm whether they describe the board or the packed carton - the two differ by the clearance and the board grade, and an order that leaves the question open can produce a carton that does not fit the planned pallet pattern. The unit belongs in the same sentence as the figure, because carton dimensions are quoted in cm by some suppliers and inches by others.
