Bake Scaler

Bake Scaler — enter your recipe and target pan, instantly scale every ingredient. A fully offline calculator: no internet, no data collected.

Most home recipes are for 6-inch pans. Want an 8-inch or 4-inch? Scale 24 cookies up to 36? Mental math always fails — especially when the pan isn't even round. Bake Scaler does the math for you, accurately, in one tap.

[11 Pan Shapes]
Round, square, hollow ring, ellipse, heart, triangle (Heron's formula), regular polygon, sector, half circle, quarter circle, plus "by total amount" for batter and cookie dough — no more "shape not supported".

[Combine Pans on Both Sides]
Original recipe fits one 6-inch round plus a square? No problem. Add multiple pans with quantities on both sides, scale to any target combination.

[Area or Volume]
Default scales by base area (standard baking practice); flip a switch and enter pan height for volume-based scaling.

[Multi-Unit + Eggs by Count]
Weight (g/kg/oz/lb/jin/liang), volume (ml/L/cup/tbsp/tsp), count (pcs/block/dozen) — each ingredient picks its own unit. Eggs by count give whole-number suggestions (3.6 → 3-4), with a gram reference (~180g).

[13 Ingredient Presets]
Flour, sugar, butter, egg, milk... 13 common ingredients, one tap to add with the default unit.

[Real-Time + Baking Keypad]
Change a number, results update instantly. A large custom keypad built for baking — accurate even with floury hands.

[Size Preview + Measuring Tips]
Original and target drawn to scale side by side. Rough measuring tips when you have no scale (with disclaimer).
