Estimating Cable Lengths Required

Since a measuring wheel can only give an estimate distance (and cable lengths required for an installation) by walking in straight paths; what would be the best formula for estimating wire runs in ceillings and hidden walls with conduits ?? I've heard some very exotic formulas used by some engineers like "Length x Width squared, then add 25 - 50% extra feets"
