Counter Mat Sizes: How to Choose Between 12×24, 18×36 and 24×48
The right counter mat size isn't the size of your counter. It's the free space left after the register, card terminal and the customer's elbows have taken theirs.
Most suppliers answer the size question with a list. Ten sizes, twelve, sometimes more, from something smaller than a sheet of paper up to a mat that covers half a bar top. A list doesn't tell you which one fits your counter.
MatCore makes counter mats in three standard sizes, 12″×24″, 18″×36″ and 24″×48″, plus custom sizes and die-cut shapes. This guide is about choosing between them, and knowing when none of them is right.
The short answer
Pick the counter mat size from the free counter space, not the counter. Measure the clear area customers actually lean on, after the register, card terminal and displays are in place. As a rough rule, 12×24 suits tight spots beside a terminal, 18×36 suits a typical checkout or reception counter, and 24×48 suits long service counters and bars.
Step 1: Measure the free space, not the counter
A counter that's 6 feet long rarely has 6 feet to give. The register, a card terminal, a tip jar, a display stand and the staff's own working space all take their share. What's left, usually the strip right in front of where customers stand, is where the mat goes.
Stand on the customer's side and measure that strip. Then take an inch or two off each side. A mat that runs into the base of a terminal gets its corners lifted every time someone moves the terminal, and a lifted corner is the first thing to wear.
- Note anything that sits on the counter permanently and has to stay off the mat.
- Check the counter edge. A mat that overhangs the front edge gets caught by bags and sleeves.
- Photograph the counter from the customer's side. It helps us suggest a size if you're unsure.
What each standard size is good for
- 12″×24″: the compact option. It fits beside a card terminal, on a narrow pharmacy or phone-shop counter, or on a reception desk where the mat also works as an oversized mouse pad. Room for one clear message or one product.
- 18″×36″: the all-rounder for most checkout and service counters. Big enough for a headline, a product range or a menu, small enough to leave the rest of the counter usable.
- 24″×48″: for long counters and bar tops where the mat is the main display. It reads from further away, but it needs a clear run of counter and more care when cleaning around it.
- Custom size or die-cut shape: when the free space is an odd shape, or when the mat itself should be the logo or product outline.
Step 2: If it's an insert-window mat, size the window first
With an insert-window counter mat, the mat size matters less than the window size. The window is what you'll be filling with printed sheets every time the promotion changes, so it should match a sheet size you can print cheaply and consistently.
Work backwards: choose the insert size your printer or head office can produce easily, add a border for the frame, and that gives you the mat size. MatCore can set the insert size, the window orientation and the number of windows to suit, so a long mat can carry two separate inserts side by side.
If the artwork will be swapped often by store staff, a magnetic flip-top counter mat is quicker to change. We compared the two formats in insert-window vs magnetic counter mats.
Step 3: Decide the orientation
Counter mats are read by the customer, not the person behind the counter. That sounds obvious until a batch arrives with the artwork facing the staff.
Decide which long edge faces the customer, and whether the mat runs along the counter (landscape) or into it (portrait). Landscape suits most checkouts. Portrait can work on a narrow reception desk where the customer leans in to sign something. Mark it on your drawing or in the enquiry.
Sizing for a chain of stores
If the mats are going into many locations, resist the urge to measure each counter individually. Group your stores by counter type and choose one or two sizes that fit nearly all of them.
Two reasons. First, fewer sizes at higher quantity is simpler to quote and produce. Second, and more important for insert-window mats, one window size means head office can print a single promotional sheet for every store. Mixed sizes mean mixed inserts, and that's where campaigns go wrong.
Common sizing mistakes
- Ordering to the full counter length, so the mat runs under the register.
- Choosing a window size no local printer can produce without trimming.
- Forgetting the counter edge, so the mat hangs over and curls.
- Approving artwork on screen without checking it at actual size. Text that looks fine on a laptop can be tiny on an 18×36 mat. Our guide to designing counter mat artwork covers this.
FAQ
What sizes do counter mats come in? MatCore's standard sizes are 12″×24″, 18″×36″ and 24″×48″. Custom sizes and die-cut shapes, such as a product outline or a logo, are also available.
What is the most common counter mat size for a checkout? For a typical checkout or reception counter, 18″×36″ is the usual starting point, but measure the free space first. Tight counters often need 12″×24″.
Can one mat have more than one insert window? Yes. The number of windows, their size and their orientation can all be specified on insert-window counter mats.
How long does production take? Stock sizes typically ship in 7–15 days and custom sizes or shapes in 20–30 days. MOQ depends on size and format and is confirmed in the quotation. Send us your counter measurements and we'll recommend a size.
