I have a 48"square table and 4 chairs and cushions...the medium size round works perfect as you can see in the pic (hopefullly that came thru). It's slightly larger so it works to cover the legs great too. Here in the Pacific Northwest we get high winds and rain and I am so impressed that this cover holds, keeps cushions dry and I used a 5 gallon bucket in the middle of the table to ensure water run-off...works perfect...thank you so much!
