A LITTLE HELP FOR YOUR NEXT BINDER PROJECT
Pokémon placeholder size in mm: 63 × 88
BinderPress exports each placeholder at 63 × 88 mm. Measure a test print rather than relying on its on-screen appearance: the reference line should be 50 mm and the trimmed insert should match the PDF dimensions.
The inch conversion matters
63 × 88 mm converts to approximately 2.48 × 3.46 inches. It is not exactly 2.5 × 3.5 inches: that would be 63.5 × 88.9 mm. When printing this app’s PDFs, preserve their intended 63 × 88 mm size instead of scaling to a rounded inch description.
Check the insert in your own pocket
Screen zoom and a binder preview do not establish a physical measurement. Print one page at Actual size, measure the reference line and both insert edges, then trim a sample and test it with the sleeve or pocket you use.
Paper feed, printer settings and trimming can affect the result. An insert’s purpose is to mark the space for a missing card; it does not need to imitate the weight, finish or authenticity of a real card.
Changing pockets does not change card size
My binder can preview 4, 9, 12 or 16 pockets per page side. Those options arrange the collection on screen. The A4 and Letter PDF layouts still use the same 63 × 88 mm insert dimensions.
Use the printing guide if the reference line or card dimensions are off. Use the page calculator if you are deciding how much binder space your selected slots need.
