How much filament is on a 1 kg spool?
Metres per kilogram from each material's typical density. Denser materials give fewer metres.
Guide
Why spool weights vary
The same brand often uses more than one kind of spool. Plastic and cardboard spools weigh different amounts, spool designs change over time, and bigger spools are heavier. Where a brand's spools vary, the table shows the most common weight and the range, so pick the exact filament in the spool calculator for the closest figure.
Empty spool weights questions
How much does an empty 1 kg filament spool weigh?
It depends on the brand and spool type. Most empty 1 kg spools weigh somewhere between about 120 g and 260 g, so the difference matters. Check the table for your brand.
Why does the same brand list different spool weights?
Many brands use more than one spool, such as plastic and cardboard versions, or have changed their spool design over the years. Picking the exact filament in the spool calculator gives the most accurate figure.
What does the ≈ sign mean?
It marks a typical weight for that brand and spool size from SpoolmanDB, rather than a figure listed for that specific filament. It is usually close, but weighing an empty spool of your own gives the exact number.
Where does the spool weight data come from?
From the Open Filament Database and SpoolmanDB, both open, community-maintained databases. SpoolmanDB also powers Spoolman, a popular tool for tracking spools. See the credits for both.
How much does a full 1 kg spool of filament weigh?
About 1.1 to 1.25 kg: the 1 kg of filament plus the empty spool. Check the empty weight for your brand above, because a heavy plastic spool can add a quarter of a kilogram.
How long is 1 kg of filament?
About 335 m of 1.75 mm PLA, or 126 m at 2.85 mm. Denser materials such as PETG give a few metres less per kilogram; the table above lists each common material.
