How Many Meters of Filament on a Spool? [Filament Calculator]

How Many Meters on a Spool?

Filament Length Calculator

Basic Spool Weight Assumed to be 248g
Calculate

This is a comprehensive list of filament materials and their lengths on 500g, 750g, 1KG and 3KG spools for both popular 1.75mm and 2.85mm sizes, based on each material’s density. This should allow you to correctly budget remaining filament for prints based on the remaining weight of your spool.

Here we explain the relationship between filament volume and length. Before we can ask how much filament is on a 1kg spool, we first need to know the weight of the empty spool. 

 

Q: How much does an empty filament spool weigh?

A: For reference, our empty spools weigh 248g. And this is approximately an industry average.

 

Our filament calculator has been made to 6 decimal places, which should be accurate enough given that manufactures resin densities are always rounded to just 2 decimal places. These lengths are meant as an accurate guide only, not a guarantee of what you will have received on your spool from other suppliers. They are however a guarantee as to what you will have received from us, had you ordered filament from us.

You might be wondering how much does PLA weigh, or any other filament for that matter. Well, we use a density figure to work out how many grams of filament in each cubic cm. This is represented as usually a figure just over 1. For example, the density of PLA filament is 1.24 grams per CM^3. 

To see how many meters is 1KG of filament, look under the 1KG spool column. Move left and right to see lengths for other spool weights.

We hope this list of lengths based on weight and density is useful to you. Now you know how many meters of ABS in a 1KG spool. Please comment below if you have any questions, and feel free to provide any constructive feedback if you feel we’ve missed anything.

Alternatively there might be a material we've missed, so you cannot work out the length of filament in 1KG spool - if yours isn't mentioned, please let us know.
