Measuring for a futon cover

Futon covers are made for different thicknesses of futons as well as width and length. To get the right thickness, it's best to measureyour futon when it is laid flat on the floor. Don't worry if the cover does not fit exactly; most covers are meant to be just a tiny bit loose. If you have a custom cover made, make absolutely sure of the measurements; most of the time custom covers can't be returned.
