Serum box size brief
A serum carton is sized from the bottle, not from the label: take the widest point of the bottle, the full height with the dropper or pump on, and add a small, deliberate clearance. This page shows what to measure, how the arithmetic works on one worked example, and what to put in the brief so Grapxo can draw the dieline at your size. There is no “every serum is X mm” table here: bottles differ too much for one.
Measure the bottle first
Measure the bottle as it will sit in the box, with the closure on. A bottle’s volume tells you little about its size: bottles of the same millilitres can differ by centimetres.
| Measure | Why it matters |
|---|---|
| Body diameter (or width and depth, if square) | Sets the inner width and depth of the box |
| Total height with the cap, dropper or pump | Sets the inner height; the closure is usually the tallest and most forgotten part |
| Widest point | A shoulder, a collar or a sleeve can be wider than the body |
| Closure type | A rubber-bulb dropper, a pump and an airless pump all stand at different heights |

Keep a physical bottle or a technical drawing next to the brief. The bottle’s supplier drawing is the best source for the height with the closure on.
Add the fit clearance
The inner size is the bottle size plus clearance. A snug fit looks better and ships better; a loose fit rattles. Several tolerances stack up here: bottles vary slightly, board has thickness, and a folded carton is never perfectly square. Plan a few millimetres, then check it on a sample instead of trusting the arithmetic. The same logic, with the internal and external size distinction, is on how to determine box size.
| Dimension | Measured on the bottle | Clearance added | Inner size |
|---|---|---|---|
| Width | 33 mm | 2 mm on each side | 37 mm |
| Depth | 33 mm | 2 mm on each side | 37 mm |
| Height | 108 mm with the dropper on | 3 mm of head room | 111 mm |

The brief for this bottle would read 37 × 37 × 111 mm, straight tuck-end carton. Your bottle is different: measure your own.
List the panels and the copy
A serum carton is narrow, so type is small and every line has to earn its place. Say in the brief what goes on which panel, and keep room for the information your market requires.
- Front: brand, product name, volume in ml.
- Sides: the variant, a short benefit line or the usage; the narrow faces suit short text.
- Back: ingredients, usage, manufacturer details and the barcode, if you supply one.
- Tuck flap and top: often the batch or lot area; leave room for it if your process prints it later.
What your market requires on a cosmetic carton depends on where you sell; confirm it with your regulator or printer. The serum and cream box page covers the category, and the dropper and airless box brief goes deeper on closures.
What to put in the brief
Write the volume in ml, the inner size in millimetres, the carton style (straight or reverse tuck end), the brand language and the fields you must show. Guessing a structure without a size is risky; update the dieline once your printer’s die is final. Open the brief in the studio, or write to info@grapxo.com with questions. Grapxo draws the dieline and the print surface together as vectors; the final die is confirmed with your printer.
Check on a white sample
Before the artwork is printed, ask for a blank die-cut sample and put the real bottle in it. Check that the closure clears the top, that the carton closes without bowing, and that the bottle can come out again without damaging the tuck. Adjust the inner size, regenerate the dieline, and only then release the print run.
Frequently asked questions
How should I measure the bottle?
Measure the body diameter (or width and depth), the total height with the cap, dropper or pump on, and the widest point. Add a physical sample or the supplier’s technical drawing to the brief when you can.
Should the box height include the dropper?
Yes. Measure the bottle with the closure on, exactly as it will sit in the box, and add head room above it.
How much space should I leave around the bottle?
A few millimetres on each side is a common starting point for a snug fit. Glass tolerance and thick board both argue for a little more. Test it on a white sample before you print.
Do 15 ml, 30 ml and 50 ml serums need different boxes?
Usually, but the volume alone does not tell you the size. Bottles of the same volume differ in diameter and height, so size the box from the bottle you actually use.
Can Grapxo make a box without dimensions?
It needs a size to draw the dieline. At least give the volume in ml and a rough size, then update the dieline when your printer’s die is locked.
Is a serum box the same as a perfume box?
The structure can be the same, a tuck-end carton, but the panel copy, the regulation and the silhouette of the product differ. See the cosmetic and perfume pages for each.
