Mines a msd I would of be a 44cm. So for something like a 60 cm I would think to multiply the measurements by 1.5 so it won't bet of big or too small since double of 44cm is 88cm which would be too big and 60cm is about the middle

I.e if a plasma television you need for msd is 4x6 then for an sd is multiply both sides with 1.5 so it would be 6x9.
