When designing custom apparel—especially for larger sizes like 4XL shirts—getting the image size right can make all the difference between a professional look and a design that feels off-balance or disproportionate. As men's sizing trends evolve in 2025, understanding the right design dimensions for XXXXL shirts is crucial for creators, brands, and style-conscious consumers.
Why Image Size Matters on a 4X Shirt
A standard image placement that works on a medium or large shirt often appears too small on a 4XL. That’s because the larger canvas of the shirt requires a proportional increase in image size to maintain visual balance. If you’re printing a front-centered design, a general rule for a 4X shirt is to go with an image size around 13-14 inches wide and 16-18 inches tall. This ensures the design doesn’t get “lost” in the shirt’s expanse.
Positioning Tips for Large-Scale Shirts
Aside from the image size, placement is key. Centering the image too high or low can throw off the entire aesthetic. It’s best to start the design around 3 inches below the collar, especially on casual tops like sleeveless shirts or sleeveless workout shirts where a muscular fit might affect how the fabric hangs.

For designs that run across the chest or back, maintaining symmetry is vital. Avoid wrapping designs too close to the armpits or seams, as this can distort the artwork on long sleeve running shirts or long sleeve athletic shirts, especially during movement.
Fabric Stretch and Print Considerations
Remember that 4X shirts, particularly athletic ones, may have different stretch ratios compared to standard sizes. Fabrics like polyester blends used in performance gear can expand during wear, slightly altering how an image looks when worn. It’s smart to test your print size on a mockup or sample shirt to check the image’s final appearance before bulk production.

Final Thoughts
Whether you’re styling your next oversized tee or creating merch for athletes, understanding how large an image should be on a 4X shirt is key to making a bold and flattering statement. From bold prints on sleeveless workout shirts love at the gym to subtle logos on long sleeve athletic shirts for runners, proper image sizing ensures that your design looks intentional and stylish—regardless of size.
