Check your custom dimensions
Measure a finished insert without its tab. Enter width and height in millimetres.
148 × 210 mm (5.827 × 8.268 in), portrait.
Your size goes to the builder without leaving this browser. Set the binding margin and layouts in the builder.
Enter the finished page size
Choose inches or millimetres and enter the width and height in the orientation you want the page generated. The builder accepts widths from 90 to 330 mm and heights from 140 to 483 mm. Measure a known insert or trusted specification rather than estimating from the planner cover.
Check the page fits your paper
To print at finished size, load paper already cut to your width and height. To print on A4 or US Letter, one page centred or two to a sheet, the page has to fit at 100%. If it doesn’t, choose larger paper, one page per sheet, or check your measurements; the builder never shrinks the page.
Set the binding margin separately
The content margin moves the writing area away from the binding edge. It is space, not a hole position, and it cannot promise that a particular punch fits. Trim first, then line the page up with your punch’s own guide.
After printing, measure the width and height. A page of the right size can still sit too close to the cover, the rings or the holes from your punch, so try one in your planner first.
