Pott'r Pottery Callipers – Compact, Practical and Easy to Adjust

Our Pott'r pottery callipers are designed to be small enough to fit into your pottery toolkit, while opening to a full 300mm span to handle most everyday measuring jobs.

At just 155mm from top to bottom, they're easy to keep close to hand when throwing or handbuilding.

Use them to measure the diameter of a pot when making a matching lid, or to check the widths and heights of pieces when making sets. They're particularly useful when you want to make several pots to the same dimensions without relying on guesswork. Consider buying a pair for those times when two diameters are needed together. 

Designed with Potters in Mind

The centre adjustment uses a stainless steel grub screw with diamond-shaped, knurled nuts that are easy to grip and tighten, even when your hands are covered in clay.

Simply adjust the callipers to the measurement you need and tighten the nuts to hold the position while you work.
