Pipe Fitter Offset Calculator

Pipe Fitter Offset Calculator gives you the cut, not just the travel. Enter the offset, tap the fitting angle and pick the elbow: travel, run and the cut length after both fitting take-offs and your root gap appear on a live drawing of the offset. Every length shows as a fraction to the nearest 1/16 or 1/32 inch with the exact decimal beside it, and a cut that rounded short is flagged in red, never hidden. Millimetres work everywhere too.

Built as a pipe fitter calculator for the job site: a big glove-friendly keypad types fractions and feet-and-inches directly (24 3/8, 2' 6 1/2), the first screen is the pipe offset calculator itself, and nothing needs a signal, an account or a login. Every pipefitter, plumber and welder gets the same answer in ten seconds. A high-contrast mode keeps the numbers readable in full sun.

What is inside:
• Simple offset: any fitting angle, 11.25° to 90°, with travel and run multipliers.
• Rolling offset: rise and roll give the true offset, travel and run, or the fitting angle a fixed advance needs.
• Parallel offsets: how far each pipe starts along the run when several lines turn together at one spacing.
• Miter calculator for segmented elbows of 2 to 10 pieces: cut angle, cutback, back and throat lengths.
• Branch, lateral and saddle cuts: ordinate tables for any header and branch size and angle.
• 1:1 wraparound templates as PDF for miters and saddles, with a scale-check ruler printed on every page.
• Fitting take-off (centre-to-end) for long and short radius elbows and tees, NPS 1/2 to 24, plus your own custom fittings when your supplier's differ.
• Pipe data: OD, ID and wall by schedule, weight empty and full of water, bore volume.
• Weld metal and filler for V-groove and fillet welds, and metal weight for plate, bar, tube, box and angle.
• Saved jobs with a cut list you can send as a PDF or text.

Dimension tables are compiled from public manufacturer catalogues and every take-off can be overridden. Verify against your fitting manufacturer's data. This pipe fitting calculator is a layout aid for trained fitters; it is not an engineering or code certification.

Simple offset and pipe data are free with no ads. Pro is a single one-time purchase through Google Play that unlocks every other calculator, the templates, saved jobs and cut-list export, custom fittings and per-calculator units. What you type stays on your phone.
