Free Ita Bag Pin Capacity Calculator & Planner
Estimate how many round pins can fit inside an ita bag display window before you buy the bag or attach a single badge. Enter the usable clear-window size, your pin diameter and the spacing you want between pins.
This is a planning estimate, not a promise of exact capacity. Zippers, seams, curved windows, holders and mixed merchandise reduce usable space.
How the estimate works
Width and height define the usable display rectangle.
The calculator adds your preferred spacing to the badge diameter.
A staggered layout can use space differently from straight rows.
What should you enter for common pins?
Measure your actual badge with a ruler when possible. If you use protective badge covers or decorative holders, measure the finished outside diameter, not the bare pin. A 58 mm pin is 5.8 cm; a 2.25 inch pin is about 5.72 cm.
Why the real number may be lower
- Clear windows often narrow near seams, curves and zippers.
- Rosettes and badge holders make a pin effectively larger.
- Photocards, acrylic charms and keychains consume irregular areas.
- Leaving negative space usually makes a display easier to read.
- Pin backs and insert structure can limit where individual badges sit.
Use the estimate as part of your ita bag planner
Once you know the approximate capacity, make a paper rectangle at the same dimensions and place your real merchandise on it. This catches spacing problems that a number alone cannot show.

Pin capacity FAQ
How many pins fit in an ita bag?
There is no single answer because window sizes and badge sizes vary. Use the calculator above with the usable display dimensions and your actual pin diameter.
Should I fill every available space?
Not necessarily. Dense badge walls can look great, but focal pieces and mixed-merch layouts often benefit from more breathing room.
Can I use this for photocards or acrylics?
The numeric calculator is designed for round pins. For mixed merchandise, use the result only as a rough reference and plan the actual layout on a removable insert or paper template.
