Filament
Typical density for this material. Use your filament's data sheet if it gives one.
Most printers use 1.75 mm; some, such as Ultimaker, use 2.85 mm. It is printed on the spool label.

- Overture (cardboard spool): 163 g comes from a single reported reading. Weigh your own empty spool to confirm it.
- 1.24 g/cm³ is a typical density for PLA (Polylactic Acid). Brands differ by a few percent, and the length changes by the same percentage. Use the density on your filament's data sheet if you have it.
How this was calculated
Weight to length, with your numbers.
How this was calculated
Weight to length, with your numbers.
Step 1: Subtract the empty spool
W_net = W_total − W_spool
= 1163 g − 163 g
= 1000 g of filamentOverture (cardboard spool) spools are taken as 163 g (one reading). Weigh one of your own empties to confirm it.
Step 2: Cross-section of 1.75 mm filament
A = π × (d ÷ 20)²
= π × (0.0875 cm)²
= 0.024053 cm²The diameter in millimetres is halved and converted to centimetres so the units match the density in g/cm³.
Step 3: Length from weight
L = W_net ÷ (ρ × A × 100)
= 1000 g ÷ (1.24 g/cm³ × 0.024053 cm² × 100)
= 335.3 mDividing by density and cross-section gives centimetres; ÷100 gives metres. A density that is 2% off makes the length 2% off.
Step 4: Electricity for the print
Cost = watts × hours ÷ 1000 × price per kWh
= 110 W × 8 h ÷ 1000 × $0.16
= $0.14110 W is an estimated average for the Bambu Lab P1S. A plug-in power meter gives your printer's real figure.

In short
An empty Overture cardboard spool weighs about 163 g (one reading). 1163 g on the scale is a full 1 kg; 663 g is half. An empty Overture plastic spool weighs about 204 g (171–237 g reported).
The calculator starts with Overture cardboard spool and PLA selected; change the material to match your spool, or pick the other spool type.
Scale reading to filament left
Each row adds the 163 g cardboard or 204 g plastic empty spool to the filament. Lengths are for 1.75 mm filament at typical densities (PLA 1.24, PETG 1.27 g/cm³).

Worked example: a full Overture cardboard spool of PLA
The three steps behind the result, using the 163 g empty weight.
Step 1: Subtract the empty spool
W_net = W_total − W_spool
= 1163 g − 163 g
= 1000 g of filamentOverture (cardboard spool) spools are taken as 163 g (one reading). Weigh one of your own empties to confirm it.
Step 2: Cross-section of 1.75 mm filament
A = π × (d ÷ 20)²
= π × (0.0875 cm)²
= 0.024053 cm²The diameter in millimetres is halved and converted to centimetres so the units match the density in g/cm³.
Step 3: Length from weight
L = W_net ÷ (ρ × A × 100)
= 1000 g ÷ (1.24 g/cm³ × 0.024053 cm² × 100)
= 335.3 mDividing by density and cross-section gives centimetres; ÷100 gives metres. A density that is 2% off makes the length 2% off.
Notes on Overture spools
- This value is a single reported reading.
- Cardboard edges can shed fibers on roller-driven feeders; some users wrap the rim with tape.
- Weigh one of your own empty spools from this brand for an exact figure.
- Overture plastic spool readings vary from 171 to 237 g.
Overture spool: common questions
Empty weight, accuracy and the scale method.
How much does an empty Overture spool weigh?
Overture 1 kg cardboard spool (Matte PLA, Super PLA+): 163 g, one reading. Overture 1 kg plastic spool: 171–237 g reported (midpoint used). Weighing one of your own empties is the most accurate figure.
How do I check how much filament is left on a Overture spool?
Weigh the spool and subtract 163 g (cardboard spool). For example, a reading of 663 g means about 500 g of filament, which is roughly 167.6 m of 1.75 mm PLA or 163.7 m of PETG.
How accurate is the empty weight?
The Overture cardboard spool figure comes from a single reported reading, so treat it as approximate. For the Overture plastic spool, reported weights run from 171 g to 237 g, so a reading can be off by up to about 33 g, or roughly 11.1 m of PLA. Weigh one of your own empty spools to remove that error.
