An easy way to measure a wheel is put the bike on a sidewalk with the valve stem in the bottom position on a crack. Roll the bike forward until the valve stem is again in the bottom position. Then just measure with a tape measure, (and convert to cm/mm if you don't have a metric tape). Change in distance due to tire deformation of a rider's weight should not be significant.
