Clay Weight Estimator

Stop guessing how much clay to wedge. Enter the shape you want to throw and Claybook calculates the starting weight, so every session begins with the right ball on the wheel.

How it works

Pick a form (cylinder, bowl, mug, plate, or vase), set your target height and width, and the estimator factors in wall thickness, floor, and typical shrinkage for your clay body. You get a gram-accurate starting weight in seconds.

Why it matters

Consistency starts before the wheel spins. When you weigh your clay to a specific target, you throw more predictable forms, waste less material, and build muscle memory faster. Production potters have done this for centuries. Now you can too, without a spreadsheet.

What you get

Pro tip

Once you find a weight that gives you a great mug, write it down (or save it in the app). Repeating the same starting weight is the fastest path to a matching set.
