How Much Wrapping Paper Do I Need

How much wrapping paper do I need? For one box, cut a sheet with length = box length + twice the height + 2 inches, and width = twice the width + twice the height + 1 inch, then multiply by gifts and divide by roll length for rolls to buy. Skip the math with our free wrapping paper calculator.

The Sheet-Size Formula

Measure the box, not the gift inside it: length is the longest side, width the shorter side, and height the thickness. Sheet length = box length + (2 x height) + 2 inches, where the 2 inches cover the fold and the overlap. Sheet width = (2 x width) + (2 x height) + 1 inch, where the 1 inch covers the end folds. For a 10 x 8 x 4-inch box, the sheet is 10 + 8 + 2 = 20 inches long and 16 + 8 + 1 = 25 inches wide, a 20 x 25-inch sheet per gift. The allowances are generous on purpose: a sheet an inch short is useless, while a sheet two inches long just gets trimmed. If you measure in centimeters, our free inches to centimeters guide converts your tape readings, and our free wrapping paper calculator accepts either unit.

From One Sheet to a Whole Pile

Count gifts by size, not by person, because one average size for a mixed pile understates the big boxes and wastes paper on the small ones. Twelve gifts in three sizes might be four 15 x 10 x 2-inch shirt boxes (21 x 25-inch sheets, 84 inches cut), four 10 x 8 x 4-inch boxes (20 x 25-inch sheets, 80 inches), and four 6 x 4 x 4-inch small boxes (16 x 17-inch sheets, 64 inches), for a total cut of 228 inches, or 19 feet. A single 30-foot roll of 30-inch paper covers that pile with 11 feet left for the inevitable forgotten gift. The mistake most people make is buying one roll, starting to wrap, and discovering halfway through that the pile needed two: counting first, in inches of cut, prevents it. If your pile is mostly one size, multiply that size's sheet length by the count and you have the total cut in one multiplication.

How Many Rolls to Buy

Divide the total cut length, in inches, by your roll's length, also in inches, and round up: rolls = total cut / roll length, rounded up, because a roll that ends 3 inches short of a sheet is finished, not almost enough. A 30-foot roll is 360 inches, so a 228-inch pile needs 228 / 360 = 0.63 rolls, which rounds up to 1 roll, while a 600-inch pile needs 600 / 360 = 1.67 rolls, which rounds up to 2. Roll width matters as much as roll length: a 24-inch roll cannot wrap a box that needs a 25-inch sheet, in either direction, and the answer then is a 36-inch roll or two pieces with a seam on the bottom. Standard retail rolls are 24, 30, and 36 inches wide, and 25 to 30 feet long, and the 30-inch roll covers most clothing and medium boxes. Buy one spare roll if more than a quarter of your gifts are large or odd-shaped, and keep the leftover: a half-used roll from this year is next year's first roll.

Odd Shapes, Cylinders, and Diagonal Wrapping

For a cylinder such as a bottle or a candle, wrap around the circumference: sheet length = circumference (pi x diameter) + 2 inches overlap, and sheet width = height + 2 inches for the end folds. For a truly irregular shape, measure its longest, widest, and tallest points, add 2 inches to each, treat those as a box, and expect 20% to 30% more paper than the box equivalent. Diagonal wrapping, where a square sheet is turned 45 degrees and the corners pulled to the centre, uses about 20% less paper in theory for a cube-shaped gift, but it is fiddly, leaves a bulky knot on top, and fails on flat shirt boxes, so use it only for small cubes you want to show off. For the ordinary pile, the rectangular sheet in the formula above is faster and wastes less of your evening, and our free wrapping paper calculator checks the roll-width fit, including a rotated-sheet fallback, before you buy.

Buying Smart, and Reusing What You Have

Holiday paper is cheapest in January and most expensive in December, so the pile you count this year is also next year's shopping list: note the roll width and count that worked, and buy that again in the sale. Plain uncoated paper recycles in most areas, while foil, metallic, and glitter papers do not, so if recyclability matters, choose uncoated paper and skip the foil, since the sheet size is the same either way. Reuse smooth, uncreased sheets from large gifts for small gifts, because the cheapest paper is the paper you already own. For holiday shopping math beyond wrapping, our guide to calculating a percentage off a sale price helps you check whether a paper deal is really a deal. And if you are timing the whole wrapping session, our free minutes to hours converter turns a pile of minutes into hours for planning, while our free centimeters to inches converter handles any metric tape readings.
