Sleeving a board game is a purchasing problem before it is a storage problem. A game may have standard poker-size cards, mini European cards, tarot cards, square cards, oversized reference cards, or several sizes in the same box. The sleeve order has to respect those groups because one pack size, one brand line, or one sleeve dimension rarely covers everything.

Card count alone is not enough. A 196-card deck and a 72-card mini deck require different sleeve sizes, and each size may be sold in 50-pack or 100-pack quantities. Reserve sleeves matter because sleeves tear, promos arrive later, expansions get mixed in, and a heavily shuffled deck wears faster than a reference card that stays on the table. Too little reserve forces a second order. Too much reserve wastes money and takes box space.

Fit is a physical margin check, not just a label match. Some packages list the card size they fit, while others list the sleeve's outside dimensions. A sleeve that is too narrow can bow or pinch cards. A sleeve with too much height or width may shuffle poorly and make deck stacks sloppy. Width usually matters first because it prevents bending, while extra height is often easier to tolerate.

Thickness changes the box after the purchase is solved. Thin sleeves cost less and add less bulk, but they may tear or feel flimsy. Premium sleeves add protection and handling quality, but hundreds of sleeved cards can overwhelm an insert or make the original box hard to close. A sensible sleeve plan therefore includes card groups, fit margins, pack rounding, reserve quantity, cost, and an approximate box-bulk check.

Edition differences are the common trap. A revised edition, promo pack, language edition, or expansion can change counts or sizes. The most reliable manifest comes from the game box, publisher component list, or a trusted sleeve-size community entry checked against the exact edition.

How to Use This Tool:

Build a sleeve manifest with one row per card group, then use the result tabs to check purchase quantity, fit, cost, and storage.

  1. Select Start from to load a sample manifest, or choose Custom manifest and paste your own rows.
  2. Enter the Sleeve manifest in the shown format: Group, Card size, Cards, Sleeve size, Pack size, and Price. Pipes, tabs, commas, semicolons, and spaced columns are accepted.
  3. Set Reserve sleeves. The calculator adds this percentage before pack rounding so damaged sleeves and future cards have a buffer.
  4. Choose Pack rounding. Consolidate matching sleeve packs for one combined shopping order, or round each card group separately when each deck must keep its own unopened packs.
  5. Select Sleeve thickness, then use Advanced fields for currency symbol, shipping cost, and available box clearance.
  6. Read Buy List for pack counts and cost, Card Groups for parsed sizes and fit checks, and Box Bulk for the added stack-height estimate.
  7. If the input hint reports ignored rows, normalize the manifest or fix missing group, size, count, sleeve size, or pack-size values before ordering.

The Shopping Note is a compact purchase summary, while the Pack Coverage Chart shows adjusted demand and spare sleeves by sleeve size.

Interpreting Results:

Buy List is the main purchase output. It groups compatible rows by sleeve size, pack size, and price unless per-group rounding is selected. Adjusted sleeves includes the reserve buffer. Sleeves bought is the actual pack-rounded total, and Spare is what remains after adjusted demand is covered.

  • Usable fit means sleeve dimensions clear the card with a modest margin.
  • Tight fit warns that at least one edge has less than 1 mm of clearance.
  • Loose fit warns that the sleeve margin may feel awkward during shuffling.
  • Size blocker means the entered sleeve dimensions are smaller than the card dimensions.
  • Storage review needed means the sleeve-thickness estimate exceeds the entered box clearance.

A purchase list with no size blocker is not proof that the selected brand will feel right. Check the exact edition, card finish, sleeve brand tolerances, insert space, and how often the deck will be shuffled.

Technical Details:

The manifest parser reads each non-empty row as a card group. It accepts named size aliases such as poker, bridge, mini European, tarot, and square, or dimensions written as width x height in millimeters. Rows without enough fields or without a card count are ignored and reported as warnings.

Formula Core

Reserve sleeves are added before pack rounding:

Sadjusted = C + ⌈ C × R100 ⌉

C is card count and R is reserve percent. Pack count is then:

Packs = ⌈ Sadjusted Spack ⌉

Box bulk is an estimate based on two film faces per sleeved card:

Added height mm = Cards×Microns×2 1000
Check Rule Meaning
Too small Sleeve width or height is below card width or height. Do not order that sleeve size for the group.
Label-size match Sleeve and card dimensions are effectively identical. The row may be using package fit size rather than sleeve dimensions.
Tight fit Width or height margin is below 1 mm. Verify brand tolerance before buying.
Loose fit Width margin exceeds 7 mm or height margin exceeds 12 mm. Cards may slide or shuffle awkwardly.
High spare count Spare sleeves exceed 35% of adjusted demand. Look for smaller packs or combine compatible rows.

Cost is pack count multiplied by pack price for each buy-list row, plus the optional order-level shipping cost. The currency symbol only changes display; it does not convert between currencies.

Accuracy Notes:

Sleeve planning depends on component data that can vary by edition and publisher run.

  • Verify the exact card count and card dimensions for the edition you own.
  • Check whether reference cards, promos, replacement cards, or expansions should be included.
  • Confirm whether a sleeve package lists card dimensions or sleeve dimensions.
  • Use the box-bulk estimate as a warning, not a guarantee of insert fit.

Worked Examples:

Mixed board game sample: A 196-card main deck at 63.5x88 mm with 8% reserve becomes 212 adjusted sleeves. If matching sleeves are sold in 100-packs, the Buy List rounds that group into three packs and shows the spare count created by pack rounding.

Deck-builder expansion: Several standard-size rows can consolidate into one buy-list row when sleeve size, pack size, and price match. That reduces unnecessary spare packs compared with rounding each deck group separately.

Bad size row: If a 70x120 mm card group is paired with a 66x92 mm sleeve, Card Groups reports a size blocker. Correct the sleeve size before trusting the Pack Coverage Chart or Shopping Note.

FAQ:

What manifest format should I paste?

Use one row per group with Group, Card size, Cards, Sleeve size, Pack size, and Price. The parser accepts pipes, tabs, commas, semicolons, or spaced columns.

Should I round by sleeve size or by card group?

Use matching sleeve-pack consolidation for one shopping order. Use per-group rounding when each deck or expansion must receive its own unopened packs.

Why does the fit check say label-size match?

Some brands list the card dimensions a sleeve fits rather than the sleeve's outside dimensions. Verify the package or brand catalog before treating it as exact clearance.

Why were some rows ignored?

Ignored rows usually lack enough fields, have no card count, or use a size string that cannot be parsed. Use Normalize manifest after fixing the rows you want to keep.
