There are two different design size choices for the front of a T-shirt: a full-front design or a left-chest design. Let’s dive into which design choice is better for you and the recommended size for each.

Full-front designs are the classic choice for T-shirt customization. Ideal for bands, brands promoting themselves, and limited edition artist shirts, these placements offer a perfect blend of visibility and style.

Left-chest design

A left-chest design is perfect for making a subtle yet impactful statement. This placement is especially suitable for your logo or creating uniforms for schools or work teams, providing a professional and cohesive look. It’s a classic choice that allows for branding or personalization without overwhelming the overall design of the T-shirt.

Back T-shirt design sizes

Just as there is a full-front design and a subtler left-chest design, there is a full-back design or a smaller back-neck design for the back of your T-shirt. You don’t have to include a back design along with a front design, but if you are looking for more ways to show off your brand, there’s plenty of room on the back!

Full-center back design

A surefire way to stand out and turn heads is to place your design on the back of your T-shirt. A full-back design is versatile across various shirt sizes and serves multiple purposes. It’s perfect for numbered sports jerseys, charity or brand names, and unique artwork that’s guaranteed to catch attention.

Recommended design size:  10″- 14 length x 10– 12 width

Back-neck design

For a minimalist and sophisticated branding approach, try placing a label on the outer back collar of your T-shirts. Positioned just below the neckline, this stylish spot is perfect for subtle branding. Keep the label visible but not overpowering to maintain the shirt’s overall design and fit.

This option is perfect in terms of keeping printing costs to a minimum, as well as for brands who are looking to promote themselves or sponsors without being too showy.

Other t-shirt design choices and their size

Did you know you can design more than just the front and back of your T-shirt? Below are two other places for you to promote your brand or art and their recommended sizes.

Sleeve design

The sleeve is a fantastic spot for a unique design or text on both short and long sleeve T-shirts. On short sleeves, this placement is perfect for showcasing logos or making a quick, bold statement. 

Long sleeves, on the other hand, provide ample space to feature names, messages, or intricate designs, allowing for more creativity and impact. For the best results, ensure your design is aligned with the centerline of the sleeve and coherent with any other designs printed on the T-shirt. 

Recommended design size for short sleeve: 3 x 3″
Recommended design size for long sleeve: 4– 15 length x 2– 4 width

  • Maximum file size: 100MB
  • Minimum image resolution size: 300dpi

Inner label design

The inner label is the ideal space for additional promotional branding and extra information. Just below the collar inside the shirt, the inner label design is perfect for logos, care instructions and sizing.

Recommended design size: 2.5 x 2.5 inches

How to prepare your T-shirt design for printing

Setup your file

The most important step in setting up your file correctly, is to look at the specific requirements of the printing studio you’re ordering from. Each printing service will most likely offer a specs guideline, a template, or a mockup generator to help you print the best quality T-shirt. This should cover:

  • print size
  • image resolution
  • minimum and maximum file size
  • what formats are accepted

Check the sizing

Whilst we’ve covered the basics of each T-shirt print sizing, make sure to double check the specific requirements of the printing provider you choose to work with. These may vary from printer to printer, so it’s always better to be safe than sorry. You should be able to find the individual specs as you upload your design, but if it isn’t shown you can contact the printers directly and ask for sizing specs.

Print colors

As with above, be sure to check with the printers if they prefer the color profile of your design to be in CMYK or RGB — though most will prefer CMYK.

In a nutshell, RGB and CMYK are color models used in digital and print media. RGB (Red, Green, and Blue) is for digital displays, combining light to produce colors on screens like monitors and TVs. CMYK (Cyan, Magenta, Yellow, and Black) is for printing and layering ink to create hues.

Formatting

Depending on which print studio you decide, you’ll need to set up your file to be compatible with what their system can print. At VistaPrint, we accept a multitude of formatting including the following file types:

  • Adobe Acrobat Document (*.pdf) (recommended)
  • Adobe Illustrator Artwork 8.01- (*.ai, *.ait) (recommended)
  • Adobe Photoshop Image (*.psd) (recommended)
  • Bitmap Image (*.bmp)
  • GIF Image (*.gif)
  • JPEG Image (*.jpg,*.jpeg)
  • Microsoft PowerPoint 2010 (or earlier) Document (*.ppt, *.pptx)
  • PNG Image (*.png)
  • TIFF Image (*.tif, *.tiff)
  • High-Efficiency Image Content (*.HEIC)

Now you’re ready to upload your design 

The last (and arguably the most satisfying) step of the process is to upload your design. By following the tips and best practices outlined in this guide, you’ll be well-equipped to create stunning T-shirt designs that fit perfectly, no matter the size. Remember, the key to achieving the best results lies in careful planning, attention to detail, and a willingness to experiment and refine your approach.
