Roof Pitch Calculator — Roof pitch (x:12) and angle from rise & run. Enter Rise (in), Run (in) to get an instant, accurate result.

נוסחה

Pitch = (rise ÷ run) × 12, expressed as X:12 — the standard US roofing convention. Angle in degrees = arctan(rise ÷ run).

דוגמה מהעולם האמיתי

Example: With Rise (in) = 6, Run (in) = 12, the Roof Pitch Calculator gives Pitch X Per 12: 6, Angle Degrees: 26.5651.

שאלות נפוצות

What does a "6:12" pitch mean?

It means the roof rises 6 inches vertically for every 12 inches (1 foot) of horizontal run — a common moderate roof slope.

How is pitch different from angle?

Pitch (X:12) is a ratio used in construction; angle in degrees is the same slope expressed trigonometrically as arctan(rise/run) — both describe identical steepness.

What inputs does the Roof Pitch Calculator need?

You'll need to provide: Rise (in), Run (in). All fields use sensible defaults, so you can see a working example immediately and then adjust the values to match your own numbers.

How accurate is the Roof Pitch Calculator?

The Roof Pitch Calculator applies the formula exactly as calculated — Pitch = (rise ÷ run) × 12, expressed as X:12 — the standard US roofing convention. Angle in degrees = arctan(rise ÷ run). — so results are precise for the inputs you provide. Accuracy depends on entering correct, realistic input values.

Is the Roof Pitch Calculator free to use?

Yes, the Roof Pitch Calculator is completely free, requires no signup, and runs instantly in your browser.

אודות מחשבון שיפוע גג

The Roof Pitch Calculator uses a real, verifiable formula — Pitch = (rise ÷ run) × 12, expressed as X:12 — the standard US roofing convention. Angle in degrees = arctan(rise ÷ run). — so results are accurate every time, not an approximation.
