You need a stamp measurment gauge. The sides should also measure perf 11. The stamp design (the colored area on the paper, not all the way to the perforation holes, would measure 19.75mm x 22.25mm. If that is the case you’ll need to send it to a stamp expertizing service like PSE in order to confirm.
