Glue Amount Calculator — How Much Cement Do You Need?

Calculate how much plastic cement or CA glue you need for your kit build.

How We Calculate This

Estimates glue quantity based on parts count, scale, glue type and application style.

Method

  • Estimated joints = Parts count × Glue usage factor (default 0.8 — roughly 80% of parts share a glued joint)
  • Total ml = Joints × ml per joint × Scale factor × Application-style factor
  • Bottles needed = Total ml ÷ Bottle size (rounded up)

These per-joint volumes (roughly 0.015–0.08 ml depending on glue type), the scale factors and the style factors are rough estimates, not manufacturer figures. Solvent cement is applied by capillary action — “just enough” to wet the seam — so real usage varies widely with technique. Treat the result as a buying guide (how many bottles to keep on hand), not a precise dose. A 1:48 aircraft kit with ~150 parts works out to about 2–3 ml of liquid cement, matching real-world experience.
