Estimate remaining filament
Enter the current total weight and the empty spool weight, pick diameter and material: the tool gives the remaining length and net filament weight.
Example
| Input | Value |
|---|---|
| Total weight | 1,000 g |
| Empty spool | 200 g |
| Filament | 800 g |
| Length (PLA 1.75) | ≈ 268 m |

Frequently asked questions
How much does an empty spool weigh?
Often 180–250 g depending on brand. Check the exact value — a wrong one skews the result.
Why choose the material?
Density varies (PLA 1.24, PETG 1.27, ABS 1.04…) and changes the length for the same weight.
Is it accurate to the metre?
It is a good estimate; real diameter and tolerances cause a slight difference.
