Coverage & Bead-Length Calculator
See how far the glue sticks you already have will go — in linear trim, or in glue dots for rhinestones, tesserae, and silk petals.
What your sticks will cover
One stick, two ways to use it
A glue stick is really a fixed volume of adhesive — what changes is how you spend it. Laid out as a continuous bead, it covers a certain number of linear inches, useful for edging a frame or trimming a box. Portioned into small dots instead, that same volume sets a certain number of individual pieces — the way mosaic tesserae, rhinestones, or silk flower petals actually get attached.
This calculator computes both from the same underlying stick volume, so you can check either figure against a project without having to run separate arithmetic for each. Both figures take off the waste allowance for the stub that never leaves the gun: the whole-stick dot count is shown as well, but it is a theoretical maximum, and the usable count is the one to plan on.
Frequently Asked Questions
How is this different from the Glue Stick Quantity Estimator?
The quantity estimator works forward from a target (how much bead length you need, to a stick count). This tool works backward from what you already have (a number of sticks, to how far they'll stretch) — handy when you want to know if the sticks in the drawer are enough before you start, rather than shopping for exactly what a project needs.
What's a "glue dot" in this calculator?
A small, roughly disc-shaped dab of glue used to set a single small item — a rhinestone, a mosaic tessera, a silk flower petal, a sequin. The calculator treats it as a short squat cylinder of a diameter and thickness you choose, and works out how many of those the volume in your sticks can produce.
Which figure should I use for a mosaic or embellishment project?
Use the dot count — it tells you roughly how many individual pieces (tiles, gems, petals) you can set with the sticks on hand. For a project that's mostly edging, trim, or a continuous line of glue instead, use the linear coverage figure.
Why does gun size (mini vs full) change the numbers so much?
A full-size 11mm stick has roughly two and a half times the cross-sectional area of a 7mm mini stick, so it holds proportionally more glue for the same length — meaning more dots or more linear coverage per stick, at the cost of less precision for fine detail work.
Educational tool only. This is a general volume-based estimate; actual coverage varies by glue-stick brand and how thickly you apply it.
