- Enter greenhouse length and width.
- Enter wall height.
- Enter roof pitch in degrees.
- Click Calculate for glazing areas.
Riferimento Rapido
| Da | A |
|---|---|
| Small (3×2×2 m, 30°) | ~28 m² glazing |
| Medium (6×3×2.5 m, 30°) | ~63 m² glazing |
| Large (10×4×3 m, 25°) | ~120 m² glazing |
| Polycarbonate 4 mm | ~2.5 kg/m² |
| Glass 3 mm | ~7.5 kg/m² |
| Optimal pitch | 25–35° |
Casi d'Uso
- •Planning a new greenhouse build.
- •Ordering polycarbonate or glass panels.
- •Estimating heating requirements.
- •Budgeting greenhouse materials.
Formula
Wall area = 2(L×H) + 2(W×H). Roof slope = (W/2)/cos(pitch). Roof area = 2 × slope × L. Gable area = W × rise.
Domande Frequenti
What is a good roof pitch?
25–35 degrees is typical for greenhouses to allow snow shed and maximize light.
Does this include the floor?
Floor area is shown separately; glazing total excludes the floor.
