How to Measure a Recessed Matwell for a Custom Logo Mat

How to Measure a Recessed Matwell for a Custom Logo Mat | Entrance Matting Ireland

Ordering a custom logo mat for a recessed entrance looks simple until you actually get the tape measure out. Get the measurements right and the finished mat drops into place like it was always meant to be there. Get them wrong, even by a centimetre, and you end up with a mat that rocks underfoot, leaves an ugly gap, or won't sit flush with the surrounding floor.

Because these mats are made to order, there's no trimming a bit off the side once it arrives. The cutting and finishing happen before it ever reaches your door, so the measurements you send across are effectively the blueprint.

In this guide, you'll learn what a recessed matwell actually is, which measurements matter most, how to take them properly, the mistakes that catch people out again and again, and what a supplier needs before they can manufacture your mat correctly. Businesses looking at custom logo mats in Ireland will find everything they need here to measure their entrance with confidence.

Quick Answer: How to Measure a Recessed Matwell

If you're short on time, here's the checklist version. You'll need to measure:

  • Width - taken inside the frame, at several points
  • Length - front to back, also at several points
  • Depth - how far down the recess sits from the surrounding floor
  • Door clearance - the gap between the door and the finished mat surface
  • Frame condition - any bends, rust or loose sections
  • Corner shape - square, rounded, or irregular
  • Drains or unusual features - anything that interrupts the flat recess

Check every one of these twice before you send them off. It takes an extra five minutes, and it's the single easiest way to avoid an expensive reordering headache.

What Is a Recessed Matwell?

A recessed matwell is a shallow, purpose-built pit set into the floor at an entrance, designed so that a mat sits flush with the surrounding surface rather than on top of it. Instead of a mat that people step up onto, the recess allows the mat to become part of the floor itself.

Commercial buildings favour this approach for good reason. Visually, a flush mat looks far tidier than a loose mat lying on tiles or stone. It doesn't curl at the corners, doesn't slide around, and doesn't create the trip hazard you get with a raised edge.

There are accessibility benefits too. A flush surface is easier for wheelchair users, pushchairs, trolleys and anyone with mobility difficulties to cross without catching a wheel or a foot. For any building open to the public, that matters.

You'll typically find recessed matwells at the entrances of:

  • Hotels
  • Office buildings
  • Retail stores
  • Schools
  • Hospitals and healthcare facilities
  • Shopping centres
  • Corporate headquarters

Most were built in when the building went up, cast into the concrete or formed with a metal frame, which means the recess itself is fixed. Your new mat has to be made to match it, not the other way round.

Why Accurate Measurements Matter

A custom logo mat is cut, bound and finished to a specific size before dispatch. Once it's made, that size is fixed, which is the whole reason this guide exists.

If the measurements sent to the supplier are even slightly off, the consequences show up immediately on installation day:

  • A mat that's too small leaves visible gaps around the edge, which look unfinished and collect dirt
  • A mat that's too big won't sit flush, so it either buckles or has to be forced in, which damages the edges
  • A mat that's too shallow for the recess sits above the surrounding floor and becomes a trip hazard
  • A mat that's too thick for the depth catches the bottom of the door every time it opens
  • Poor fit reduces how well the mat actually scrapes and traps dirt, which is the whole point of having one

None of these problems can be fixed by trimming or stretching after the fact. Coir, rubber and other matting materials don't stretch to cover a measuring error, and cutting down an oversized mat on-site rarely leaves a neat, bound edge. Getting it right first time is genuinely the only reliable option.

Tools You'll Need

You don't need anything specialist. A basic kit will do the job properly:

  • Steel tape measure - more accurate than a fabric or plastic one, which can stretch slightly over time
  • Notebook - to record every measurement as you take it, rather than trying to remember them
  • Pen - obvious, but easy to forget
  • Smartphone - for photographs and as a backup measuring aid
  • Torch - useful for checking depth and inspecting the frame in poorly lit entrances
  • Straight edge - a spirit level or a length of timber works well for checking whether the recess floor is level
  • Spirit level (optional) - helpful if you suspect the recess has settled unevenly over time

A steel tape makes a real difference here. Fabric tapes can sag or stretch under tension, introducing small errors that add up across a wide entrance.

Step-by-Step Measuring Guide

  1. Step 1: Measure the Width
    Measure the width inside the frame of the recess, not the outer edge of the surrounding floor tiles or the wall-to-wall distance. The mat needs to fit inside the recess itself, so that's the measurement that counts. Measure three points: one near each end and one in the middle. Older recesses are rarely perfectly consistent. If you find variation, record the smallest figure.
  2. Step 2: Measure the Length
    Length is measured front to back, from the inside edge of the frame nearest the door through to the inside edge at the far side of the recess. Check this at more than one point, ideally at both sides of the recess as well as the centre. Write down the actual figures you get, not rounded ones. If one reading comes back at 1187mm and another at 1193mm, record both rather than calling it "about 1190mm".

    A practical example: a hotel entrance in Dublin measured 1200mm at one side and 1194mm at the other. The mat was manufactured to the smaller figure, giving a neat finish rather than one forced into the tighter end.
  3. Step 3: Measure the Matwell Depth
    Depth is arguably the most important measurement of all, determining how thick the finished mat can be while sitting flush. Measure from the top of the surrounding floor down to the base of the recess, laying your straight edge across the opening if direct measurement is awkward. Check depth at several points.

    This is why depth matters when ordering a customised coir logo mat for an existing recess, since coir matting comes in specific thicknesses and the supplier needs to match one to your actual depth.
  4. Step 4: Check Door Clearance
    Door clearance is the gap between the bottom of the door (in both open and closed positions) and the surface of the finished mat. Open the door fully and check clearance, then close it and check again, paying attention to inward-opening doors.
  5. Step 5: Inspect the Frame
    Look for bent/warped frame sections, loose edges, rust at joints, cracked sections, uneven spots, or missing frame sections. A damaged frame can throw off your measurements.
  6. Step 6: Look for Drains, Thresholds and Obstructions
    Check for drainage channels, floor drains, threshold strips, expansion joints, sloped sections, or raised lips. A supplier who knows about obstructions before manufacturing can plan for them.
  7. Step 7: Photograph the Entrance
    Take a full entrance shot, close-up of the recess, clear frame shot, doorway opening angle, side profile depth shot, and close-ups of any drainage or damage.

Common Measuring Mistakes

⚠️ 1. Measuring Outside Frame

Measuring floor tiles instead of inner recess frame gives an oversized figure.

⚠️ 2. Ignoring Depth

Skipping depth results in a mat sitting too high or low relative to the floor.

⚠️ 3. Forgetting Door Clearance

Inward-opening doors catching or rubbing across the finished mat surface.

⚠️ 4. Rounding Measurements

Rounding 1187mm to 1190mm is the difference between a snug fit and buckle.

⚠️ 5. Single Measurement Point

Assuming older buildings are perfectly uniform without checking multiple spots.

⚠️ 6. Ignoring Damaged Frames

Bent or lifted metal frames distort readings and cause fitting issues.

⚠️ 7. Assuming Perfect Right Angles

Recesses out of square cause corner gaps if not checked in advance.

Measuring Best Practices

Should You Measure More Than Once?

Yes, always. Measure twice, and check several points across the width, length and depth rather than relying on a single central reading. Have a second person confirm key figures where possible.

Can You Measure an Existing Mat Instead?

It's tempting to simply measure the mat already sitting in the recess, but existing mats shrink slightly over time (especially natural coir fibres) and wear down. Measuring the recess itself is far more reliable.

What Information Should You Send When Requesting a Quote?

A complete set of information helps a supplier recommend the right specification first time:

  • Width (inside frame)
  • Length (front to back)
  • Depth (floor to base)
  • Door clearance (open and closed)
  • Photographs of the entrance
  • Location type (indoor or outdoor)
  • Typical foot traffic levels
  • Type of business
  • Logo artwork
  • Preferred delivery date

Frequently Asked Questions

How do I measure a recessed matwell?
Measure width and length inside the frame at several points, check depth from the surrounding floor to the base of the recess, and confirm door clearance. Record the smallest figures where readings vary.
Should I measure inside or outside the frame?
Always inside the frame. The mat needs to fit within the recess, so measuring the outer floor or wall-to-wall distance gives an inaccurate, oversized figure.
What if my matwell isn't perfectly square?
Check the corner angles as well as the straight measurements. If the recess is noticeably out of square, mention this to your supplier along with photographs.
Why is depth important?
Depth determines how thick the mat can be while still sitting flush with the surrounding floor. Get it wrong, and the mat either sits below floor level or stands proud, both trip hazards.
Can a recessed mat be trimmed after manufacture?
Not reliably. Custom mats are cut, bound and finished before dispatch, and trimming afterwards can damage the edge finish.
What happens if I order the wrong size?
The mat won't fit properly. It may leave gaps, sit unevenly, catch the door, or need reordering entirely, which costs time and money.
Do all recessed entrances have the same depth?
No. Depth varies considerably between buildings, particularly older versus newer construction, so it should always be measured individually.
Should I include the frame in my measurements?
No, measure inside the frame's inner edge. The frame itself isn't part of the space the mat needs to occupy.
Can I replace an existing recessed mat?
Yes, but it's best to measure the recess itself rather than the old mat, since existing mats can shrink or wear unevenly over time.
Should I send photographs with my measurements?
Yes. Photographs confirm your measurements are consistent with what's actually there and often reveal details, like drainage or frame damage, that are easy to miss.

Conclusion

Taking the time to measure a recessed matwell properly, rather than rushing through it, is what separates a mat that fits perfectly from one that causes problems from day one. Width, length, depth and door clearance all play their part, and none should be skipped.

Double-check every figure, take your photographs, and note anything unusual about the frame, drainage or floor before requesting a quote. If you'd like guidance, send us your measurements for a custom recommendation, along with your entrance photographs and logo artwork, and we'll help you work out exactly what will fit.
