Use the Pottery Shape Generator to explore ceramic vessel proportions, estimate clay weight, check throwability and export a clean blueprint PDF for studio work.
Best on tablet or desktop. On phone, rotate your screen to landscape mode.
Start with the Reset button if you want a balanced starter form.
Adjust the height, top diameter, shoulder, belly, lower body and base.
Use clay estimate as a practical starting point, not an absolute rule.
Use throwability feedback to notice risky proportions before making.
Turn shrinkage on when you want working dimensions before firing.
Export a PDF when the form is ready to print, save or take into the studio.
For cups and smaller vessels
Keep the height moderate, avoid an extreme belly and keep the base stable.
For open bowls
Use a wider top diameter and watch how the base and lower body support the form.
For vases
Pay attention to narrow openings, tall height and strong belly transitions.
For teaching
Use the same form with small changes and compare how the difficulty and clay estimate shift.
