The perfect size to roll up and fit in the playmat compartment of an UltraGuard 550+; there are other sellers on etsy who make playmats that I really like, but are just slightly to long ("long" when rolled up). This mat is also the perfect size to fit inside the various 3d printed tubes that various etsy stores sell for storing playmats; some of the other mats I have are 3mm thick instead of 2mm, and won't fit in a normal size tube.
In addition to this playmat, I've also purchased several custom playmats, even requesting that the lines for the zones be made lighter; bot the lines and the artwork I supplied turned out great.
I've found the owner to be very helpful and responsive. I have no hesitancy in recommending these playmats.
The Matt came out perfect. I love the design and the martial is solid.
