D10 next to A10

The calculation runs out at D10. It would be the geometric mean of A10 (26 × 37 mm) and a B11 that was never standardised. On paper, B11 would be 22 × 31 mm. D10 relates to A10 just like every other D size: sides about 8 % shorter, roughly 85 % of the area.

Cutting D10 from A10

You cannot buy D10 paper ready-made. The easiest way is to trim an A10 sheet: 2 mm off the width and 3 mm off the height. With pieces this small, a craft knife, a steel ruler and a cutting mat are more accurate than scissors.
