Easiest way to measure it I found,was mark a line on the ground, place your wheel with the valve on the mark.Go 1 complete reveloution and mark it again,then measure from line to line.

Or put a dab of paint on the tyre, do 1 and a half revolutions and you'll have to lines on the pavement. Measure that distance.

I've never found those measurements to be very accurate - wheels are slightly different and tyres are certainly different.

I always just mark a line on the pavement and check one rotation - remember to be on the bike too as your weight makes a slight difference.
