How to measure a bottle or tub
- Height. Measure the flat label panel between the shoulder and the base. Take 2–3 mm off the top and bottom so the label doesn’t ride onto curves.
- Diameter. Measure across the panel with calipers, or wrap a strip of paper round it and measure the strip.
- Wrap length. Circumference = π × diameter. For a label that doesn’t meet, take off a 3–5 mm gap. For a clear label that overlaps, add 5–10 mm.
Example: a bottle 48 mm across has a circumference of 151 mm. Leave a 5 mm gap and the label is 146 mm long.

When everything won’t fit
Small packs must still carry all mandatory text at a 1.2 mm x-height. If it won’t fit:
- Use the full wraparound, not a front-and-back pair.
- Move marketing copy to the front and give the back panel to the law.
- Use a peel-and-reveal label, which adds a second printed layer.
