Pipe Offset Calc: Rise & Roll

Calculate a pipe offset and cut length on site in under 20 seconds — without converting fractions or remembering trigonometric multipliers. Pipe Offset Calculator is built for pipefitters, plumbers, HVAC installers, welders, and fabricators who need fast, accurate offset math in the field. SIMPLE AND ROLLING OFFSETS Simple two-elbow offset: enter the offset and a fitting angle, get Travel and Run instantly. Rolling offset: enter rise and roll, get True Offset, Travel, Run, and Roll Angle. Common angle presets: 22.5, 30, 45, 60 degrees. BUILT FOR THE FIELD Feet, inches, mixed fractions, and decimal inches — enter measurements exactly the way you would write them on a tape measure, like 2' 3 1/4". Metric millimeters are supported throughout, with one tap to switch units — values you already entered convert automatically. Results update live as you type. No Calculate button, no waiting. CUT PIECE Deduct both fitting takeouts to get the exact cut-piece length between fittings — center-to-end dimensions, calculated the way you would verify them by hand. REFERENCE TABLE A built-in multiplier table for every common angle, for when you just need the number and not the app. WORKS OFFLINE, RESPECTS YOUR PRIVACY No account, no network connection, no ads, no analytics, no subscription. Every calculation happens entirely on your device. Pipe Offset Calculator only stores your unit and rounding preference, locally, on your phone. Field measurements and fitting manufacturer data remain authoritative — always confirm before fabrication or cutting.
