TRIM GAUGE / CONVERSION NOTES

1. Start with the physical width and height of the artwork.
2. Convert millimetres to inches by dividing each dimension by 25.4.
3. Multiply both inch values by the desired pixels per inch.
4. Round each result to the nearest whole pixel.

Example: 210 x 297 mm at 300 PPI rounds to 2480 x 3508 px.
The calculation measures the rectangle you entered. For bleed, add
the extra margin to both sides of each dimension before converting.
