Free pipe cut list calculator — straight tube cutting plans

Calculate a cutting plan for straight pipe or tube sections. Use finished lengths from your drawing and keep each diameter, wall thickness and material in a separate order.

CSV format and example

Open the template in Excel or another spreadsheet editor. Keep the header names length, quantity, label. Enter lengths in the selected units and positive whole quantities, up to 200 parts in total. Names are optional. Save as CSV UTF-8, then import it here. Import replaces the parts list; stock settings stay as entered.

Leave quantity blank for unlimited stock. Add reusable offcuts as finite stock rows. Use only one material and cross-section per order.

Required parts

Part nameLengthQuantity

CSV columns: length, quantity, label (optional). Lengths use the selected units. Import replaces the parts list.

Enter positive lengths and whole quantities, up to 200 parts. Every part must fit after both end trims. Kerf and trim must be zero or positive.

Cutting plan

The planner searches for a complete layout using less total stock length, then fewer stock pieces. Its bounded search may miss a better layout. Check dimensions, blade kerf and material before cutting.

Choose the matching paper size, use 100% scale and turn off browser headers and footers. Save as PDF from your print dialog if available.

Worked example: four sections from a 6 m tube

Choose millimetres. Enter stock length 6000 and available quantity 1, kerf 3 and end trim 5 per end. These values describe this example, not a recommended blade width or trim for every pipe.

Required parts
Part name	Length (mm)	Quantity
A	1500	2
B	1200	2

Check the result

One tube supplies all four sections. Finished parts total 5400 mm. Four separating cuts consume 12 mm, the two end trims consume 10 mm, and 578 mm remains: 5400 + 12 + 10 + 578 = 6000 mm. The finished parts use 90% of the stock length.

From your drawing to the saw

Enter cut lengths, not the overall assembled dimensions. Account for fitting insertion, weld gaps and other joint allowances in your drawing before using the calculator. Preserve each drawing reference in Part name. Calculate your own order, check every dimension and then print or save the workshop sheet as PDF from the print dialog.

Using an offcut on the next order

Measure the remaining tube after cutting. On your next order, add its usable length as an available stock row with quantity 1. Keep it separate from other diameters or materials. The planner does not manage inventory, calculate bends, draw pipe notches or plan angled joints.

How to use it

Enter the stock lengths and available quantities, blade kerf and end trim. Add each part length, quantity and optional name, or import a CSV. Calculate, check the offcuts, then print the workshop sheet. Save an order file to move it to another browser.

How are kerf and end trim counted?

End trim is removed from both ends of each stock piece. Between parts, a cut consumes the blade-width kerf. At the stock end, only the material remaining beyond the finished part is removed, up to one kerf; an exact fit needs no cut. Parts, kerf, trim and offcut are counted separately.
