One facet, six times
Each panel is a trapezoid, wide at the bottom and narrow at the top. The same template is used six times: bevel the slanted edges and the vase closes in as it rises.

The measurements you enter become a flat pattern, ready to cut.
Each panel is a trapezoid, wide at the bottom and narrow at the top. The same template is used six times: bevel the slanted edges and the vase closes in as it rises.
A regular polygon, one side per facet. Each side matches the bottom of a panel exactly: the base sets the building order.
The panels lean inward up to the neck. Choose anywhere from 3 to 12 panels in the tool.

PITFALL NO. 1
−12%
Clay shrinks 10 to 15% as it dries and fires. A template drawn to the finished size always gives a vase that is too small — the most common hand-building mistake, and you only see it when the kiln opens.
You enter the size of the finished piece: the tool works out the rest.
A downloaded pattern only works for one clay and one size. Here, change one value and everything recalculates.
— IN PRACTICE
Nothing to install, no account. Your browser is enough — keep the computer for printing.
1
Enter the diameter, the height, the slab thickness and your clay’s shrinkage. The template updates live.
2
Print your pottery template at 100% — never “fit to page”. A 50 mm check bar on every sheet lets you verify the scale with a ruler.
3
Paper on the slab, knife around it, once per facet. The panels go up one by one around the base, with bevelled edges.
— FOR REFERENCE
Start from these, then adjust to your clay and your tests.
| Vase | Panels | Ø base → top | Height |
|---|---|---|---|
| Bud vase | 6 | 70 → 30 mm | 150 mm |
| Bouquet vase | 6 | 130 → 80 mm | 140 mm |
| Tall vase | 8 | 120 → 70 mm | 220 mm |
| Large vase | 8 | 160 → 100 mm | 280 mm |
| Trumpet vase | 6 | 80 → 140 mm | 180 mm |
— FREQUENTLY ASKED QUESTIONS
Cut the facets and the base from a 5–6 mm slab, bevel the slanted edges, then build the panels up one by one around the base, joining each seam with slip. The template gives you one facet to repeat and the polygon base.
Six panels give a crisp shape that’s easy to build. Eight panels look closer to a round vase. The tool takes 3 to 12 facets.
Roughly 180° divided by the number of panels: 30° for six, 22.5° for eight. Fine-tune as you assemble; the edges draw closer as they rise.
Yes. A top Ø smaller than the base gives a vase that closes in, like a bud vase. A larger top Ø gives a flared, trumpet-shaped vase. A top Ø of 0 gives a point.
Yes, it’s free and needs no sign-up. Set your measurements, then export a PDF or print directly.

You can print directly or export your template as PDF or SVG.
The library includes cups, mugs, bowls, chawans, plates, serving dishes, bottles, jugs, boxes and vases. Every shape adjusts to your measurements.
No. The templates are made for slab building, no wheel needed.
Yes, the tool offers US Letter as well as A4. Pick the size that matches your printer before exporting.
Check your clay’s data sheet or measure a test tile after firing. Then enter the shrinkage in the tool and fine-tune with your tests.

— WHAT YOU PRINT
Two kinds of pieces: identical facets that form the wall, and a base. Six facets by default, anywhere from 3 to 12. The tool works it all out from the measurements you enter.
Each panel is a trapezoid, wide at the bottom and narrow at the top. The same template is used six times: bevel the slanted edges and the vase closes in as it rises.
A regular polygon, one side per facet. Each side matches the bottom of a panel exactly: the base sets the building order.
The panels lean inward up to the neck. Choose anywhere from 3 to 12 panels in the tool.

— IN PRACTICE
Three steps
Keep the computer close, then head to the workbench.
1
Shrinkage depends on your clay: enter it to get an accurate template.
2
Never “fit to page”. A 50 mm check bar on every sheet lets you verify the scale with a ruler.
3
Paper on the slab, knife around it, once per facet. The panels go up one by one around the base, with bevelled edges.
FOR REFERENCE
If you’re not sure which shrinkage to use, start from the value given by your clay supplier.
| Vase | Panels | Ø base → top | Height |
|---|---|---|---|
| Bud vase | 6 | 70 → 30 mm | 150 mm |
| Bouquet vase | 6 | 130 → 80 mm | 140 mm |
| Tall vase | 8 | 120 → 70 mm | 220 mm |
| Large vase | 8 | 160 → 100 mm | 280 mm |
| Trumpet vase | 6 | 80 → 140 mm | 180 mm |
Diameters measured corner to corner, as in the tool. Suggested thickness: 5–6 mm up to 20 cm tall, 6–8 mm above.
