TrueOffset - Pipe & Conduit

The pipe offset calculator that stays out of your way: travel, run, rolling offsets, cut lengths and mitered elbows, drawn from your numbers, with no ads jumping in front of them.

NO POP-UP ADS. EVER.
One small banner at the bottom, hidden while you type. No full-screen ads, no videos, nothing that clears your numbers when you hit a button.

SEE THE OFFSET BEFORE YOU CUT
Every result comes with a drawing: the offset with its travel and run, the rolling offset seen along the pipe and from the side, each segment of a mitered elbow, the parallel runs with their start marks, the drain slope over its run. Change a number and the drawing follows.

TYPE IT LIKE YOUR TAPE READS
14 1/2", 5' 3 1/2", 3/4", 2.5m — feet, inches and fractions just work. Results come out to the nearest 1/16" (or 1/8", 1/32") with feet-and-inches next to long lengths. Prefer big keys? Turn on the app keypad in Settings: ft, in, fractions and Next, easy with gloves.

PIPE TOOLS
• Pipe offset — travel and run for 11¼°, 22½°, 30°, 45°, 60° or any angle, with the multipliers
• Rolling offset — true offset, travel, run and how far to roll the fitting; or the fitting angle for a set run
• Parallel offsets — several pipes through the same offset: where each next pipe starts so the spacing stays equal
• Cut length — center-to-center minus both fitting take-outs and the weld gaps, plus the take-out of an elbow cut to any angle
• Mitered elbow — segmented elbow from straight pipe: cut angle, long and short side of every segment, end pieces and take-out
• Pipe slope — drop over a run at ¼", ⅛" or any slope per foot, or the slope from a measured drop, with the IPC Table 704.1 minimums for the drain size
Offsets work the same for conduit: the travel is the distance between your bend marks.

WHY CLEAN SCREEN APPS
I got tired of apps that throw full-screen ads at you in the middle of a job, so I build apps with no pop-up ads. TrueOffset is the second one, after TrueSquare Calc.

Results are estimates. Check your fittings' take-out dimensions and your local plumbing and electrical codes before you cut.
