Filament Length & Usage Calculator
In short, Find out exactly how many meters or feet of filament are coiled on your spool based on material density and diameter, plus estimate how many prints you can complete.
1. Material & Diameter Specifications
Standard spools are 1,000g (1 kg). Sample coils ~250g.
Filament Density & Length Yield per 1kg (1.75mm) Spool
| Polymer Type | Specific Density (g/cm³) | Total Length per 1kg (m) | Standard 3DBenchy Yield (~12g) |
|---|---|---|---|
| PLA (Polylactic Acid) | 1.24 g/cm³ | ~335 meters | ~83 Benchies |
| PETG | 1.27 g/cm³ | ~327 meters | ~81 Benchies |
| ABS / ASA | 1.04 – 1.07 g/cm³ | ~388 – 400 meters | ~97 Benchies |
| TPU 95A Flexible | 1.21 g/cm³ | ~343 meters | ~85 Benchies |
| PA-CF (Carbon Nylon) | 1.18 g/cm³ | ~352 meters | ~88 Benchies |
