SPOOL SIZE GUIDE
Choosing between 1 kg, 3 kg and 5 kg
Spool size decides how often a printer stops, how much packaging you pay for and how much filament sits open at once.
Which size fits your volume?
| Spool size | Length (PLA, 1.75 mm) | Changes per 100 kg | Best for |
|---|---|---|---|
| 1 kg | about 335 m | 100 | Color range, testing, resale to makers |
| 3 kg | about 1,000 m | 34 | Studios and small farms, long jobs |
| 5 kg | about 1,675 m | 20 | Farms running core colors all day |
Typical lengths for PLA at 1.75 mm. PETG and other grades vary slightly with density.
Every size is wound from the same filament to the same ±0.02 mm tolerance. Only the run time between spool changes is different.
Resellers mostly sell 1 kg spools, because that is what makers buy. Farms and studios move their busiest colors to 3 kg or 5 kg and leave the rest on 1 kg.

What a bigger spool saves, and what it costs
80% fewer changeovers
A 5 kg spool runs five times longer than a 1 kg spool before someone has to swap it.
Less packaging per kilogram
One spool, one bag and one box carry five times the filament.
Needs a bigger holder
Wider and heavier. Check holders, enclosures and feed paths before ordering a full run.
Less variety on the shelf
Five kilograms of one color is a lot to keep open. Leave slow colors on 1 kg spools.
