Here is the formula...

For a Standard 4:3 screen:

Width = Diagonal X 0.8

Height = Diagonal X 0.6

SO, a 32 inch 4:3 screen is 25.6 inches wide and 19.2 tall.

For a 16:9 Widescreen:

Width = Diagonal X 0.87157552765421

Height = Diagonal X 0.490261259680549

SO, a 43 inch 16:9 screen is 36.6 inches wide and 20.6 inches tall.
