Height; 8 - 8.5 cm.

Shape book 'A'
The shape book also lists two larger sizes, 3/4 Pint and 1 Pint. No example of either is recorded. 1 Pint would be a very large mug, almost 600 ml capacity.

Dimensions in the shape book are as thrown, before firing. Allowing for shrinkage and converting from inches, the two larger mugs would be about 9.5 and 11 cm tall respectively.

Green mug on right un-numbered, others incised 73.
Double-handle variant.
