I also google the mm to inches. It will tell you how many inches the design is.
See you got your answer 25mm is approx 1 inch. That's how I judge my designs.
5cm x 8.4 cm or are you wanting it in imperial measurements?
I always have to compute the other way,but my daughter bought my a mess.tape with both.
2inch x 3 3/8inch
