How this calculator works
The paper has to go all the way around the box, and a little beyond each end so that the end flaps can fold flat. Going around the box covers the top, both sides and the bottom (2 × width + 2 × height), plus an overlap for the seam. Along the box, the paper needs the box length plus the height (half the height at each end), and 2 cm for tolerance.
Worked example: a 30 × 23 × 10 cm box needs 2 × 33 + 3 = 69 cm around and 30 + 10 + 2 = 42 cm along: a piece 69.0 × 42.0 cm. A roll 70 cm wide is too narrow to take two pieces side by side, so the pieces run along the roll, and a 3 m (300 cm) roll gives 7 pieces. A single band of ribbon takes 1.11 m, and a crossed bow 1.96 m.
Small boxes fit more than one piece across the roll. A 10 × 8 × 3 cm gift-card box needs a 25.0 × 15.0 cm piece, so several fit side by side across a 70 cm roll, and a 3 m roll gives 48 of them.
The 70 cm by 3 m default is a common size on UK shelves but not a standard, so enter the width and length printed on your own roll.
Assumptions and sources
- Centre the box on the paper, bring the long edges together over the top and tape the seam, then fold the ends like an envelope. Cut a little extra if the paper has a pattern you want to match, and for very soft or very thick paper.
The formula and a worked example are shown above, so you can check any result by hand. Read how we calculate and check our numbers. Results are estimates for planning: supplier products vary, so check the size printed on the label.
Tips before you buy
- If the sheet is too small, the box shows through at the seam and the ends. Cut generously, then trim.
- Use double-sided tape for a clean seam, and fold the ends crisply for neat corners.
- A box wider than the roll needs two pieces joined at an edge. Hide the join under a ribbon.
- Check your roll: UK rolls vary in width and length, and a short roll can wrap far fewer presents than a longer one of the same price.
- Brown kraft paper is cheap by the roll and looks good with ribbon or string.

Frequently asked questions
How much wrapping paper do I need for a box?
Around the box: 2 × (width + height) plus a 2 to 5 cm overlap. Along the box: length plus height plus 2 cm. A 30 × 23 × 10 cm box needs a piece about 69.0 × 42.0 cm.
How many presents will a roll of wrapping paper wrap?
It depends on the box and the roll. A 3 m by 70 cm roll wraps about 7 boxes the size of a shoebox (30 × 23 × 10 cm), and many more small ones. Rolls vary, so enter the size on your label.
How much ribbon do I need for a gift?
One band around the box is 2 × (width + height) plus about 45 cm for a bow: 1.11 m for this box. A crossed ribbon needs about 2.0 m.
