Pipe Offset & Cut Calculator

Work out pipe offset travel and the length to cut. Enter your measurements and fitting take-out, then see the result with the formula, substituted values and assumptions.

The simple-offset calculator is free. Solve from rise and run, rise and angle, run and angle, travel and angle, or rise and travel. Enter imperial fractions, decimal inches or millimetres. Use a 1/8, 1/16 or 1/32-inch display grid and common angle shortcuts.

Review the proportioned triangle and the working before using a result. Display rounding describes the number shown; it is not a fitting tolerance or field-accuracy guarantee. Unsupported measurements produce an explanation rather than a cut length.

A one-time Pro purchase adds rolling offsets, reusable fitting take-outs you enter yourself, joint gaps, saved cuts and printable job cards. Saved cuts retain entries, results and assumptions. Up to 100 are kept; saving another removes the oldest. Printing uses Android's system print screen and the services available on the device. Restore purchases is included, with no subscription.

Calculations run locally. There are no ads or mandatory accounts. Measurements and saved cuts stay in private app storage. Printing sends a job card to the service you choose; buying or restoring uses Google Play, and privacy/support links open web pages.

Verify measurements and fitting data before cutting. No manufacturer fitting tables or code-compliance certification are supplied. The model assumes straight, rigid pipe between fittings and does not allow for bend radius, spring, thermal movement or wall thickness.
