Baseball Card Size
A standard baseball card is 2.5 x 3.5 inches, or 63.5 x 88.9 mm. Every modern card from Topps, Panini and Upper Deck uses that size, and the entire sleeve, top loader and binder-page industry is built around it. Cards made before the late 1950s were often a different size.
The Standard Size, in Every Unit
The baseball card is specified in inches, so the inch figures are exact and the metric ones are conversions. That is the reverse of trading card games such as Magic and Pokemon, which are specified at 63 x 88 mm.

Baseball, basketball, football, hockey — all the same
The 2.5 x 3.5 inch standard is not specific to baseball. Basketball, football, hockey and soccer cards use the same size, which is why one binder, one box and one style of sleeve serves a collection across every sport. If you are searching for the size of a football or basketball card, this is the same answer.
Sizes Before the Standard
If a card does not fit a modern sleeve, it is probably older than the standard rather than damaged. These are the sizes most often encountered, and they are nominal figures — pre-standard cards were cut by many printers and varied.
| Era | Size | Notes |
|---|---|---|
| Tobacco era, about 1909-1911 | 1 7/16 x 2 5/8 in | Commonly cited for T206-era cards. Pre-dates any industry standard, and sizes varied by printer. |
| Early 1950s | 2 5/8 x 3 3/4 in | Commonly cited for the 1952 Topps set — noticeably larger than a modern card. |
| Late 1950s to today | 2 1/2 x 3 1/2 in | The standard that stuck, and the size the whole sleeve and holder industry is built around. |
Minis are a separate case: they are modern insert cards deliberately made smaller than the base card, commonly cited at about 2.125 x 3.25 inches (54.0 x 82.5 mm).
What a Standard Card Fits
A 2.5 x 3.5 inch card fits all of the following without modification. Nine-pocket binder pages hold that size in a 3 x 3 grid, which is why a page holds nine.
Penny sleeve (soft sleeve)

Making a Custom Baseball Card at This Size
The finished card is 2.5 x 3.5 inches; the artwork has to be bigger. These are Snapshot's own press numbers, so a card built here comes out at exactly the size the rest of a collection is stored at.

The same 5:7 proportions at poster scale, so one design fits both.
Photograph with room around the player
A 5:7 portrait crop is tighter than a phone photo. Leaving space above the head and below the knees gives the template somewhere to place a name plate and stats.
Keep stats and names inside the safe margin
Anything within about 1/8 inch of the edge risks being trimmed. Card backs are where this bites most, because stat lines run close to the border.
The builder handles the maths
You do not have to set up bleed or resolution yourself. Upload a photo, choose a template, and the print file is produced at the right size automatically.
Baseball Card Size Questions
What size is a baseball card?
A standard baseball card is 2.5 x 3.5 inches, which is 63.5 x 88.9 millimetres. Every modern card from Topps, Panini and Upper Deck uses this size, and it is the size that fits standard penny sleeves, 3 x 4 inch top loaders and nine-pocket binder pages.
Have baseball cards always been 2.5 x 3.5 inches?
No. The 2.5 x 3.5 inch standard dates from the late 1950s. Before that, sizes varied widely by printer: tobacco-era cards from around 1909 to 1911 are commonly cited at about 1 7/16 x 2 5/8 inches, and early 1950s Topps cards were larger than today at roughly 2 5/8 x 3 3/4 inches.
What are baseball card dimensions in mm?
A standard baseball card is 63.5 x 88.9 millimetres. That is the exact conversion of 2.5 x 3.5 inches, which is the size the card is actually specified in. Trading card games such as Magic and Pokemon are specified metrically at 63 x 88 mm, which is half a millimetre narrower.
How thick is a baseball card?
Card thickness is measured in points, where one point is one thousandth of an inch. Modern base cards are commonly around 20 point, and thicker premium and relic cards run to 35 point and beyond. Thickness matters when choosing top loaders, which are sold by point rating.
Will custom baseball cards fit my sleeves and binder pages?
Yes, if they are cut to 2.5 x 3.5 inches. Snapshot cards are cut to exactly that size, so they fit penny sleeves, standard top loaders, magnetic cases and nine-pocket binder pages alongside the rest of a collection. No trimming or special holders are needed.
What size should I make a custom baseball card file?
Build artwork at 2.625 x 3.625 inches for a 2.5 x 3.5 inch finished card. The extra 1/16 inch on each side is bleed, which the trimmer cuts away. At Snapshot's 450 DPI print resolution that is 1181 x 1631 pixels.
What is a mini baseball card?
A mini is a smaller insert card, most associated with the Allen & Ginter sets and commonly cited at about 2 1/8 x 3 1/4 inches. Minis are deliberately undersized against the 2.5 x 3.5 inch base card, which is why they need their own sleeves rather than standard ones.
