Quite a bit smaller than I expected but works just fine for me as I don't really need a big area anyway. Would recommend cutting out a piece of paper using the mousepad measurement to see if it will be big enough for u.
The surface is nice and smooth, though I've never really used a 'bad' mousepad so. Would be nice if the edges were stiched, I can imagine that this will fray in the long run.
As an extensive Counter Strike player, I can safely say that this is by far the best gaming mat I've used in a long time. It has more than enough size even for players with low sensitivity/an eDPI of 800-1000. Can't imagine the entire space being used with a higher sense, but it's nice to have all that extra room just in case.
