Before you act
- Internal usable dimensions must be verified. A nominal sleeve-size label may describe an external dimension or a target card size.
- The per-size choice minimizes that group’s entered pack cost before consolidation. It is a practical heuristic, not a proof of the cheapest global basket.
- Insert fit, box lid lift, sleeved-card thickness, stock, language, and replacement-part availability are not verified by this calculation.
Calculation notes & limitations
Repeated component IDs are counted once only when the complete records agree. Conflicting edition or expansion records are rejected.
Required sleeves are rounded per card-size group after adding allowance; groups using the same SKU are combined before pack rounding.
Sleeving mode "Outer only" adds 0 mm to each card size's width and height before matching sleeve candidates.
The standard sleeve-size reference table lists generic, widely used size families for a quick sanity check; it is not a verified per-game lookup.
Count the components before the packs.
Worked example: 220 cards become 231 sleeves
Example: 220 cards + 5% allowance = 231 sleeves; 3 packs at $21 entered. Shipping, tax, and unmatched sizes are excluded.
Use internal usable dimensions
Enter usable internal dimensions from the specification; nominal labels can differ. Keep the candidate SKU beside its pack count.
Consolidate before purchase
Review duplicate IDs and expansions. Check the exact edition, print run, and packaging before purchase.

The method is part of the tool.
Identify the exact game edition, language, print run, base components, and expansions. Give each included component group a stable ID.
Group matching measured card sizes, add a spare allowance, and filter sleeves by internal usable dimensions.
Choose a transparent per-group pack-cost candidate and consolidate identical SKUs before rounding the final basket.

Sleeve size guides

Sleeve totals for common collection sizes, by allowance and pack size.Spare-sleeve allowance guides
How each allowance percentage changes the sleeves needed for your collection.Good questions. Clear answers.
Does a matching internal sleeve size guarantee my cards will fit?
No. Internal usable dimensions must be verified against your own sleeve stock. A nominal sleeve-size label can describe an external dimension or a target card size rather than the true internal clearance.
What does the spare-sleeve allowance do?
It adds the entered percentage on top of your counted cards per group before rounding up to full packs, so you have spares for damaged or replaced sleeves.
How does sleeving mode change the fit check?
Outer only checks the raw card size. Inner only and Double sleeve add the entered film thickness (doubled for Double sleeve) to the size that the next layer must clear, since sleeved cards are larger than bare cards.
Are my card and sleeve measurements uploaded anywhere?
No. Calculations run in your browser. Saved plans use this browser’s local storage only, and CSV or JSON exports stay on your device unless you share them yourself.
Can I import my own card and sleeve records instead of typing them?
Yes. Download the CSV template for either table, fill in your measured records, and import it. Imports replace the matching table and are processed locally, never uploaded.
Why are sleeve candidates grouped and rounded per card size?
Required sleeves are rounded up per card-size group after adding your allowance, and groups that resolve to the same SKU are combined before the final pack count is rounded, to avoid buying more packs than necessary.
