Crate Pad Size Finder

The right crate pad size is your crate’s measured interior length and width, minus any allowance you choose. The pad must be no larger than that. Enter your measurements below to get a target pad size and the closest pad size listed in our dated shelf snapshot.

1. Choose inches or centimeters. If you switch later, the values you already typed are converted in place.
2. Measure the inside of the crate floor from wall to wall along the longest side. This is the interior length.
3. Measure the inside floor across the short side. This is the interior width. If you enter them the other way round, the tool swaps them for you and shows the swapped values.
4. If your crate floor is tapered, curved or rounded (common on plastic and travel crates), measure only the flat floor area and treat the result as an estimate.
5. Optionally enter an allowance. It is subtracted from both length and width. It starts at 0 because we found no published allowance.
6. Turn on the chewer filter if you only want listings whose title states chew resistance. This filter uses seller wording only.
7. Select Find pad size. You get the target pad size, the closest listed pad size, the total clearance by dimension, and the matching listings with ASIN, full listing title, quoted size fragment and snapshot date.

Do not use the crate’s advertised size, such as “36-inch”, as the pad size. On the MidWest iCrate product page we checked, crates are labelled by a nominal size and the dimensions listed are exterior dimensions, so a pad must be smaller than those numbers. Measure the inside of your own crate either way.

The finder uses one formula: target pad = (interior length − allowance) × (interior width − allowance). Centimeters are converted to inches by dividing by 2.54, the exact definition of the inch. Comparisons use your full, unrounded measurement; only displayed numbers are rounded. A pad fits when its length is no more than the target length and its width is no more than the target width.

Among the distinct pad sizes found in our snapshot, the tool picks the fitting size with the largest area. That is the “closest pad size”. If no listed size fits, it shows the smallest listed size and labels it “larger than your target”.

Total clearance by dimension is the crate interior minus the pad size, for length and width separately. It is measured against the interior, not the allowance-adjusted target. It is the total free space across that dimension, not the space on each side. If the pad is centered, each physical side gets half of the total. For example, 1 in of total width clearance leaves about 0.5 in on each side. A negative value means the pad exceeds that interior dimension by that amount.

The “standard sizes” in this tool are only the sizes we could read from listing titles, not an industry list. In our snapshot dated 2026-09-27, 12 of 38 pad and bed listings had a size we could read; 26 had no readable size and are not used for matching.

The chewer filter keeps only listings whose title contains “chew” together with “proof” or “resistant” (including hyphen and space variants). Only 1 sized listing in the snapshot matched, with the title phrase “Chew Proof”. We quote this as the seller’s claim; we do not verify or endorse it. “No chew claim found” means the phrase is not in the title, not that the pad lacks chew resistance. If no pad of your size has a chew phrase, the tool says so and does not relax the filter.

For reference only, the MidWest iCrate product page lists these exterior dimensions (single-door, length × width). Interior sizes are not stated on that page, so a pad must be smaller and you still need to measure inside the crate.

Pad sizes come from our own snapshot of non-sponsored listings in the dog crates and kennels category. Listings were classed as pads or beds by title (pad, bed, mat, cushion), de-duplicated, with cat-only beds removed. Sizes were parsed from titles in the form “A x B” (with optional inch marks or “in”), and normalised so length is at least width. Only titles were used, so no images or descriptions were copied. The allowance default is 0 because no published allowance was found. The result reports total clearance by dimension (crate interior minus pad); a centered pad has half of it on each side, and negative values mean the pad exceeds that interior dimension.

Results are size estimates from your own measurements and seller listing text, not welfare, safety or behaviour advice. Seller terms such as “chew-proof” are the seller’s claims, which we quote and do not verify or endorse. For questions about your dog’s chewing, anxiety or comfort, please talk to a veterinarian or qualified trainer (see the crate anxiety guide below).
