Pottery Thickness Measuring Caliper

Measure clay walls, bowl bottoms, plate bases, and hard-to-reach ceramic forms with our Pottery Thickness Measuring Caliper, a lightweight 3D printed tool designed for ceramic artists, pottery studios, sculptors, and craft makers.

This laced-design pottery caliper helps you check the thickness of clay pieces while working with slab-built forms, wheel-thrown bowls, sculptural objects, molds, plates, and handmade ceramic tableware.

Designed and made by DIY Project Depot in France, it combines practical studio use with a modern open-frame design.

Size and measuring range

Tool length: 25 cm / 9.8 in
Measuring range: 0–245 mm / 0–9.6 in

The equal distance between both measuring ends makes it easy to measure one side and mirror the same distance on the other side. This is especially useful for checking tricky spots, inside diameters, curved forms, bowl walls, plate bases, and areas that are difficult to reach with a standard ruler.

Made for pottery and clay work

This tool is ideal for:

• Measuring clay wall thickness
• Checking ceramic bowl and plate bases
• Measuring inside diameters and curved forms
• Working with slump molds and hump molds
• Adjusting slab-built pottery
• Checking sculptural clay pieces
• Teaching pottery classes and studio workshops
• Keeping handmade ceramic pieces more consistent

Lightweight, practical, and reusable

The caliper is 3D printed from plant-based bioplastic and assembled with a durable metal-to-metal screw for smooth adjustment and repeated studio use. The open laced structure keeps the tool lightweight while maintaining a strong and functional shape.
