Dumpling Wrapper Size Calculator
Calculate the right dumpling wrapper size for your filling amount.
Find ideal diameter for gyoza, potstickers, dim sum, and more.
Dumpling wrappers come in many shapes and sizes, and the size you need depends on the type of dumpling you’re making and how much filling you want to use. Getting the ratio right is the difference between dumplings that seal perfectly and ones that burst open during cooking.
Common Dumpling Types and Wrapper Sizes
| Dumpling Type | Origin | Wrapper Diameter | Filling Amount |
|---|---|---|---|
| Wontons | China | 7–8 cm (2.75–3 in) | 8–10 g |
| Gyoza (pan-fried) | Japan | 8–9 cm (3–3.5 in) | 10–12 g |
| Xiaolongbao (soup) | China (Shanghai) | 8–9 cm (3–3.5 in) | 10–12 g |
| Potsticker | China | 9–10 cm (3.5–4 in) | 12–15 g |
| Mandu | Korea | 9–11 cm (3.5–4.5 in) | 12–18 g |
| Pierogi | Poland/Eastern Europe | 9–11 cm (3.5–4.5 in) | 15–20 g |
| Har Gow (steamed) | China (Cantonese) | 10–11 cm (4–4.5 in) | 15–18 g |
| Empanada (small) | Latin America | 10–12 cm (4–5 in) | 20–25 g |
Gyoza and potstickers get treated as the same thing in English, and they are close cousins, but the potsticker is the bigger one. A gyoza wrapper is thinner and the pleating finer, which is why Japanese gyoza come out delicate and Chinese potstickers come out substantial. They are separate options above for that reason.
The Filling Ratio Rule
The standard rule is: filling should be about 1/3 of the finished dumpling volume. When you place filling in the center, you need enough wrapper edge (about 1.5–2 cm) to fold and crimp securely. Too much filling and the wrapper can’t close. Too little and the dumpling will be mostly dough.
Sizing from the filling
There is no clean equation here, and anyone who gives you one is dressing up a lookup table. The filling sits as a rough ball in the middle, the wrapper has to wrap over it, and then you still need a flat rim of 1.5 to 2 cm all the way round to pleat and seal. Because the ball grows as the cube root of its weight while the rim you need stays about constant, the sensible sizes land in bands rather than on a curve:
- 8–10 g filling → 8–9 cm wrapper
- 10–15 g filling → 9–10 cm wrapper
- 15–20 g filling → 10–12 cm wrapper
- 20–25 g filling → 12–14 cm wrapper
Pick the smaller end of a band if you pleat tightly, the larger end if you are new to it and want margin for error.
Thickness Tips
Hand-rolled wrappers should be thinner at the edges (for easier crimping) and slightly thicker in the center (to hold the filling without tearing). Machine-cut wrappers from the store are uniform — they work fine but are less flexible for folding intricate pleats.
For steamed dumplings, use thinner wrappers (1–1.5 mm). For pan-fried, slightly thicker wrappers (2 mm) hold up better to the crisping process.
