To start, open Photoshop and create a new document. Baseball cards are typically 2.5 inches wide by 3.5 inches tall, so set your dimensions to those measurements. The resolution can be 300 pixels/inch. Set the background content as a solid color, white is usually used for baseball cards.

Now it’s time to add graphics and text. You’ll want to find or create the following elements: a player photo, team logo, player name, uniform number, position, batting and pitching stats. For the photo, search online for images of the player you want to feature. Make sure to only use high quality, high resolution photos without a background. Resize the photo to around 1.5-2 inches wide and place it near the top center of the card.

For the team logo, you can look up logos online or create your own stylized logos in Photoshop. Place the logo to the left or right of the photo. Use a large, bold font like Helvetica for the player’s name and position, centered above the photo. Make the font size around 24-36 points. Add the uniform number below the name in a slightly smaller font size.

To include stats, look up the player’s career stats online and choose relevant categories like batting average, home runs, RBIs, ERA, wins, etc. to include on the card. You can design simple stat boxes or sections and place them below the photo. Use a condensed font in 8-12 point size for the stat text. Make sure all text is clear and legible when printed at a small size.

Now it’s time to add graphic elements and borders to finish off the design. Baseball cards often include elements like price stickers, holograms, foil logos or other embellishments. In Photoshop, you can use shapes, patterns, textures, layer styles and effects to mimic these authentic touches. Add a thin 1-2 point white or gray border around the entire card composition.

You’ll also want to include fine print text for statistics legal disclaimers and copyright information on the back of the card. Flip the document and add a gray or white backdrop. Include categories like “Career Statistics”, “How Acquired”, “Biography” and include placeholder or sample text in 8-10 point font. Don’t forget copyright and trademark symbols.

When all the main elements are arranged, use layers and the Alignment, Distribution and Snap tools to precisely position everything. Check for consistency in fonts, spacing, margins. Adjust opacity and effects as desired. Use the Crop tool to tightly trim away excess whitespace around the edges. Save the file as a high-quality JPEG or PDF for printing.

Print your baseball card design on cardstock using an inkjet or laser printer in true to size 2.5×3.5 inches. For a authentic look, consider rounded edges by cutting with scissors or card punches. Optional steps include laminating cards for protection and drilling small holes in the tops for storing in sheets or boxes like real cards.

With some digital design skills and attention to details, you can create realistic looking baseball cards of any players from any era in Photoshop. Taking the time for graphics, text formatting and laying everything out precisely will make your cards look like the real things that baseball card collectors enjoy.
