My game table is 7ft6in x 3ft. The fleece game mat that I bought a couple of months ago for my game table was a 7' x 5'; too short for my table lengthways and too long for the across the table.
I trimmed 6" off it length ways to give me a 1ft gap; then cut ~1ft8in off it the other way to give a mat 6ft6in by 3ft3in ; then I used part of the offcuts to fill the gap. There is an overlap, which has visible edge due to the thickness of the fleece mat.
That visible overlap......
