Bread Loaf Size Calculator Formula
Understand the math behind the bread loaf size calculator. Each variable explained with a worked example.
Formulas Used
Total Dough Weight
dough_weight = round(dough_weight_g)Flour (approx 60% of dough)
flour_g = round(dough_weight_g * 0.6)Water (approx 35% of dough)
water_g = round(dough_weight_g * 0.35)Pan Volume
pan_volume = round(pan_volume_cu_in)Variables
| Variable | Description | Default |
|---|---|---|
pan_length_in | Pan Length(in) | 9 |
pan_width_in | Pan Width(in) | 5 |
pan_height_in | Pan Height(in) | 3 |
pan_volume_cu_in | Derived value= pan_length_in * pan_width_in * pan_height_in | calculated |
dough_weight_g | Derived value= pan_volume_cu_in * 6.5 | calculated |
How It Works
How Bread Loaf Size Is Calculated
Formula
Dough Weight = Pan Volume (cu in) x 6.5 g/cu in
Bread dough should fill the pan about 2/3 full before rising. The dough will rise to fill the pan and dome slightly above it during baking.
Common Pan Sizes
| Pan Size | Volume | Dough Weight | |----------|--------|-------------| | 8.5 x 4.5 x 2.5 | 96 cu in | 620 g | | 9 x 5 x 3 | 135 cu in | 878 g | | 10 x 5 x 3 | 150 cu in | 975 g |
Worked Example
Calculate dough for a 9 x 5 x 3 inch loaf pan.
pan_length_in = 9pan_width_in = 5pan_height_in = 3
- 01Pan volume = 9 x 5 x 3 = 135 cu in.
- 02Dough weight = 135 x 6.5 = 878 g.
- 03Flour = 878 x 0.6 = 527 g.
- 04Water = 878 x 0.35 = 307 g.
