Node / Wafer DPW Comparison
Lock your die size and compare how many dies fit — and what each die costs — across wafer sizes. A quick way to reason about 200 mm vs 300 mm and find the sweet spot for your volume and budget.

Wafer sizes to compare
200 mm (8")268 dies
300 mm (12")633 dies
| Wafer | DPW | Util. | Wafer $ | $/die |
|---|---|---|---|---|
| 200 mm (8") | 268 | 85.3% | $13.060 | |
| 300 mm (12") | 633 | 89.6% | $18.957 |
Larger wafers fit far more dies, but cost more — the $/die column shows the trade-off for your specific die. Edit wafer cost per size to model your quoted prices.

WHY WAFER SIZE MATTERS
The 8-inch vs 12-inch effect
For the same die, moving to a larger wafer roughly doubles usable area. The calculator below turns that into exact DPW and $/die for your dimensions.
What to watch
- Moving from 200 mm to 300 mm roughly doubles usable area, but wafer cost rises too — compare $/die, not just DPW.
- Small dies gain the most from larger wafers; very large dies are edge-limited either way.
- For MPW/shuttle, the right wafer size is also driven by which shuttles your target foundry actually runs.
See which foundries run which shuttles on the MPW schedule page.
