Even if it doesn't I've heard places like Lowes and Home Depot will cut it for you. Bear in mind to measure the inside of your tank down to 1/8 of an inch. This will give you the most accurate fit. And I'd buy extra of the same tiles, in case you break one accidentally.
haha I feel the exact opposite, I used to have carpet and my gecko would always get his toes stuck in it and his mouth when he went for those crickets. not too mention taking everything out of his tank to get the carpet out to clean. So I thought if it was me I would rather have some nice lime/sandstone tiles since they do love rocky hilly terrain naturally and now my floor temp does not exceed 95 degrees anymore as those carpets are pretty thin...and my tank does not look like a putt putt course anymore!!!
I had a problem finding some that would fit my 15 gallon so I just bought one for a 20 gallon and cut it down to size. So try getting a size bigger that what you need and just cut it down. Repti-carpet never seems to expensive at the places I see it at, and it's nice to have at least 2 of them so you can switch one out while you wash the other.
