The standard K-pop photocard size
The most widely recognized K-pop photocard dimension is approximately 55 × 85 mm. That portrait proportion is familiar because it fits comfortably inside sleeves, binders, and trading card pages. The exact finished size can vary by album, unofficial printer, or custom project, so treat 55 × 85 mm as the starting reference rather than a guarantee for every product.
A digital design should preserve that portrait ratio from the beginning. If you build a card in a wide or square canvas and crop it later, faces and text can shift too close to the edge. SakuraDIY's card editor keeps the photocard composition visible while you adjust the image, border, and typography.
Bleed, trim, and safe area in plain English
The trim line is where the printer intends to cut. The bleed area extends beyond that line so tiny cutting variations do not create a white edge. The safe area is the inner region where faces, names, and important details should stay. These three areas work together: artwork can extend outward, but essential content should stay comfortably inside.
On a small card, a few millimeters make a visible difference. A title that looks safely placed on a monitor may feel cramped after cutting. Keep the main face and text inside the editor's safe boundary, and use the bleed zone for background color or decorative artwork rather than critical information.
Common card formats compared
Different fandom products use different proportions. A standard K-pop photocard is portrait and compact. A trading card may be a similar height but can use a different corner radius or print specification. Polaroid-style fan cards are often wider or have a larger lower caption area. Mini prints and postcard designs are larger and should not be forced into a photocard sleeve.
Always ask the printer for the finished trim size, bleed requirement, color profile, and accepted file format. If you are making a personal digital card, the standard proportion is enough to start. If you are preparing a group project or physical run, use the supplier's specification as the final authority.
Pixel dimensions for digital exports
Millimeters describe the physical result, while pixels describe the digital file. The pixel size depends on the intended print resolution. At 300 dpi, a 55 × 85 mm card is roughly 650 × 1004 pixels before bleed. A printer may request a larger working file, and SakuraDIY export options let you choose a resolution that matches your workflow.
Do not judge sharpness only by zooming into a browser preview. Check the final downloaded file, because the browser may scale it to fit the screen. For a professional print, keep the original export, avoid repeated recompression, and follow the printer's exact color and bleed instructions.
How to choose sleeves and print specifications
Measure the finished card before buying sleeves or binder pages. A sleeve should be slightly larger than the card so it can slide in without bending, but not so loose that the card moves around. Product listings sometimes use the outer sleeve measurement rather than the usable inner space, so compare both numbers and check whether rounded corners change the fit.
For custom printing, send the supplier the finished trim size and ask how much bleed they require on every side. A common request is several millimeters of bleed, but the exact value belongs to the printer's production setup. Also confirm whether the supplier adds rounded corners after trimming and whether front and back files must be submitted separately.
Save a master copy of the design before converting or compressing it for another service. Name the files clearly with front and back suffixes, and keep social-media previews separate from print-ready exports. This prevents a compressed preview from accidentally becoming the manufacturing file.

Step-by-step with SakuraDIY
Confirm the finished size
Use 55 × 85 mm as a common K-pop reference, then confirm the printer's exact trim size if the card will be manufactured.
Keep important details safe
Put faces, names, and signatures inside the pink safe boundary. Let backgrounds extend toward the bleed area.
Preview at actual scale
Use the SakuraDIY editor preview to judge crop, text size, and edge spacing before exporting the file.
Frequently asked questions
What is the standard photocard size in mm?
A common K-pop photocard reference is 55 × 85 mm. Individual albums and printers may vary, so confirm the required finished size for a physical order.
Should a photocard design include bleed?
Yes, physical print files normally need bleed beyond the trim line. Keep backgrounds and borders extended while keeping important faces and text inside the safe area.
Are K-pop photocards the same size as trading cards?
Not always. K-pop photocards are commonly around 55 × 85 mm, while many trading cards use approximately 63 × 88 mm. Check the sleeve or printer specification you plan to use.
