Specify trim size and extra artwork at each print edge

Calculate the supplied artwork dimensions without confusing a per-edge margin with a total addition.

Declare trim and per-edge additions

Synthetic print brief requires final trim 100 × 150 mm and two millimetres of extra artwork on every edge. Its required supplied artwork is 104 × 154 mm. These dimensions are the fictional job’s requirements, not a print standard. The example does not assess resolution, colour or a specific file format.

  3. Add both opposite edges
  4. Compare supplied dimensions

Unknown units or asymmetric edge requirements need clarification before using the equal-edge formula.

The brief changes to three millimetres on every edge. What artwork size is required?

Show the worked answer

106 × 156 mm: add 3 + 3 to the width and to the height.

Keep the trim and edge inputs in the downloadable brief so a single artwork-size field does not hide how the result was obtained.
