Pipe Fitter: Offset Calculator

Pipe Fitter: Offset Calculator does the pipefitting math you do every day — fast, exact, and in the fractions you actually mark. OFFSET • Travel and run for 11¼°, 22½°, 30°, 45°, 60° or any angle, with the constant shown (45° = set × 1.414) • Cut length between two elbows: picks the B16.9 take-out for your pipe size, long or short radius, and subtracts the root gap ROLLING OFFSET • Set + roll → true offset, travel, run, and how far to roll the fittings • Fixed run? Solve for the fitting angle that closes it PARALLEL OFFSETS • The shift that keeps the spread equal through an offset in a rack, for 2 to 6 pipes MITER CUTS • Cut angle, cut-back from the centerline, and long-side / short-side lengths for 2- to 6-piece miters on any radius FITTING TAKE-OUTS • ASME B16.9 butt-weld 90° and 45° elbows, short-radius elbows, tees and reducers, ½″ to 24″ • Elbows cut to any angle: radius × tan(½ angle) BUILT FOR THE JOB • Big keypad for feet, inches and fractions — easy with gloves • Answers to the nearest 1/8, 1/16 or 1/32″ with the exact decimal underneath, or work in millimetres • Clear drawings show what every number means • Light and dark mode • Works offline. No ads, no account, no data collected. Pipe Fitter is a calculator. Check every measurement against your drawings and the fittings in your hand before you cut. Fitting dimensions are for ASME B16.9 butt-weld fittings; socket-weld, threaded, grooved and copper fittings differ.
