Actual filter size is usually ¼ to ½ inch smaller than its nominal size. To convert actual to nominal size, measure the filter and round each dimension to the nearest inch. The nominal size is only an estimate from the manufacturer and is used for consistency. Whole house filters are always 4, 5 or 6 inches thick.
