OffsetKit: Pipe Calculator

Solve simple and rolling pipe offsets without ads, accounts, or internet access.

OffsetKit turns your measurements into clear centerline geometry you can inspect before fabrication. Enter tape fractions or metric values, choose a bend angle, and see the values behind the result.

Built for fast field entry:

- Simple offsets with travel, run, and shrink
- Rolling offsets with true offset, travel, run, and rotation
- Imperial tape fractions or metric measurements
- Common bend-angle shortcuts plus manual angle entry
- Clear labeled diagrams and calculation details
- Optional saved calculations with your own short names
- Light, dark, and high-contrast display options

Need a straight connector length? Open Connector deductions and enter your own start takeout, end takeout, start gap, and end gap. Each value is treated as a deduction along the diagonal connector. OffsetKit subtracts only the values you enter and keeps the underlying offset geometry visible.

Your work stays on your device. OffsetKit has no account, ads, analytics, tracking, cloud sync, or internet permission. Saved calculations and settings are stored locally, and backups are disabled.

Important: OffsetKit calculates geometry only. It does not apply fitting tables, pipe schedules, bend-radius development, pressure rules, welding preparation, building or trade codes, or fabrication tolerances. Travel is the diagonal centerline distance between bend centers and is not automatically the pipe cut length. Verify every input, deduction, field dimension, and shop practice before cutting or installing material.
