Pipe Offset Calculator is a great app to help with your pipe calculations.

Calculate pipe lengths more efficiently and reduce waste through incorrect calculations. Forget the 'fit by eye' and use this app to get a great fit between pipes.

Using the simple yet effective interface, you can carry out various calculations to determine the travel / set and run for pipes.

Using industry standard pipe angles such as 22.5 45 and 60 degrees, you can use any one of the 3 calculator functions to help with your pipe calculations.

Function 1 - Simple Offset Calculator
Enter the travel to calculate the run or enter the run to calculate the set all based on 3 industry standard angles.

Function 2 - Calculate the Set / Travel or Run
Use this function to calculate the travel , set or run between two pipe fittings. Using this feature allows you to position a pipe fitting precisely or measure a joining pipe precisely.

Function 3 - Rolling Offset.
Need to calculate the offset between two pipes that are on different horizontal and vertical positions? Don;t worry as you can use this feature to calculate the setback and diagonal required for the pipe. Enter the rise and offset and the calculator will determine the diagonal length of pipe required and the setback between the two pipe fittings. Choose from industry standard fitting angles to customise the calculations to your specific needs.

I haven't field applied this yet but I have been looking for an app like this. We don't do a lot of plumbing but the hardest thing for me is to figure two 45's and have then accurately be where I want them. This takes all the guess work out. Would be nice to also have a page for using two 45's in place of one 90's. Update used it the first time in the field today worked pretty good was a little unclear where to take the measurements from. Maybe spell it out a little better for us not so keen on this kind of stuff. But still worth the price

I bought the app. I used it a couple of times , now it crashes every time I use the rolling offset. That is why I bought it. Tried reloading it. Still causes it to crash. Fix it please now !
Thanks !

Kind of useless


This app doesn't take into account for your fitting loss. So basically all it's doing is multiplying your run by 1.414. I can do that with my calculator.
