What is Gift Wrap Paper?
The Gift Wrap Paper calculation tells you your paper needed (with overlap) from a few simple inputs. The figure you are solving for here is the paper needed (with overlap).
The Gift Wrap Paper formula
The core formula is:
Paper needed (with overlap) = 2 × (Box length × Box width + Box length × Box height + Box width × Box height) × 1.15Here is what each input means:
- Box length — a value measured in cm. Example: 30 cm.
- Box width — a value measured in cm. Example: 20 cm.
- Box height — a value measured in cm. Example: 10 cm.
How to calculate it step by step
- Write down the box length (for example, 30 cm).
- Write down the box width (for example, 20 cm).
- Write down the box height (for example, 10 cm).
- Apply the formula above to get your paper needed (with overlap).
- Double-check the result with the Gift Wrap Paper Calculator.
Worked examples
Example 1
| Input / Output | Value |
|---|---|
| Box length | 30 cm |
| Box width | 20 cm |
| Box height | 10 cm |
| Paper needed (with overlap) | 2,530 |
With box length of 30 cm, box width of 20 cm and box height of 10 cm, the paper needed (with overlap) works out to 2,530.
Example 2
With box length of 60 cm, box width of 20 cm and box height of 10 cm, the paper needed (with overlap) works out to 4,600.
| Result | Value |
|---|---|
| Paper needed (with overlap) | 4,600 |
Example 3
With box length of 15 cm, box width of 20 cm and box height of 10 cm, the paper needed (with overlap) works out to 1,495.
| Result | Value |
|---|---|
| Paper needed (with overlap) | 1,495 |
Tips for an accurate result
- Keep your units consistent — mixing, say, months with years or grams with kilograms is the most common source of error.
- Round only at the very end. Rounding inputs early can shift the final answer noticeably.
- Re-run the numbers whenever an input changes, rather than estimating from an old result.
