How many bundles of shingles for a 12×16 shed?
Quick Answer
A 12×16 shed with a 4:12 gable roof needs approximately 8–10 bundles of shingles total, including field shingles, starter strip, and ridge cap. The roof area is about 275 sq ft (both sides), adding 15% waste brings it to 316 sq ft — about 9.5 bundles. Round up to 10.
Quick Reference Table
| Roof pitch | Bundles (12×16 shed) |
|---|---|
| 3:12 gable | 7–8 bundles total |
| 4:12 gable | 9–10 bundles total |
| 6:12 gable | 10–12 bundles total |
| 8:12 gable | 12–14 bundles total |
How to Calculate It Yourself
- 1
One roof face at 4:12: rake = √(6² + 16²) = 17.09 ft. Area = 12 × 17.09 = 205 sq ft.
- 2
Wait — for a 12×16 shed the ridge runs 16 ft, each side is 12/2 = 6 ft wide. Rake = √(6² + 16²)? No: rake = √(run² + rise²) where run = 6 ft, rise = 6×(4/12) = 2 ft. Rake = √(36+4) = 6.32 ft. One face = 16 × 6.32 = 101 sq ft.

Two faces: 202 sq ft. Add 15% waste: 232 sq ft ÷ 33 = 7 bundles field shingles.
- 4
Add 1 bundle starter + 1 bundle ridge cap (16 lin ft ÷ 35 = under 1 bundle). Total: 9 bundles.
Pro Tip
Buying a 10-bundle minimum (a full pallet row) is often cheaper per bundle than buying individual bundles. Check with your lumber yard — at 10+ bundles you may qualify for a contractor discount.
