How much larger should a banknote sleeve be?

A practical fit usually leaves a few millimetres of clearance in each dimension. The note should enter without pressure but should not slide freely through a much larger holder.

Can a photo reveal exact banknote dimensions?

Not by itself. Without a reliable scale reference, a photo can support issue identification but not exact physical measurement. Enter the measured width and height for the best result.

Which sleeve materials are suitable for banknotes?

Look for clearly identified, PVC-free polyester, polypropylene, or polyethylene. Do not rely on the word archival without a named material and product specifications.

Are product dimensions always the usable inside size?

No. Listings may show external dimensions, and seams, rounded corners, or closures can reduce usable space. Confirm the internal pocket or holder dimensions.

Find the right banknote sleeve size

Upload one clear photo and optionally add the note's measurements to find a practical internal sleeve size, safe material, and fit checks.

Match the banknote to a properly fitted holder

A photo helps identify the issue. Exact width and height in millimetres produce the most reliable sleeve recommendation.

How to choose a banknote sleeve size

Measure the banknote itself, choose internal holder dimensions with modest handling clearance, and confirm the material is explicitly identified as PVC-free polyester, polypropylene, or polyethylene.

Measure width and height

Use a millimetre ruler without pressing or bending the note. Measure the paper, not an existing enclosure.

Allow modest clearance

Choose internal dimensions slightly larger than the note so edges and corners are not forced, while avoiding excessive sliding space.

Verify the material and seams

Check the product's internal dimensions, seam placement, closure, and named PVC-free material before buying.
