The Ultimate DPI Guide for Printing Quality T-Shirts
Printing custom t-shirts has never been easier!
With advanced printing technology, it’s now possible (and easier) to print vibrant, high-quality designs that stand out in a crowd. However, truly achieving this level of quality requires an understanding of DPI and its role in t-shirt printing.
We’ve totally got you covered with everything t-shirt printing, don’t worry.
In this ultimate guide, we’ll explore everything you need to know about photo print resolution and how to use the right DPI to create amazing custom t-shirt designs.
What is DPI?
DPI, or dots per inch, is a measure of the resolution of an image.
In custom t-shirt printing, this refers to the number of dots of ink that can be printed in a square inch. The higher the DPI, the more detail and sharpness can be achieved in the printed image.
A higher DPI will result in better digital (DTG) printing quality, allowing finer details and smoother lines to be printed. However, the optimal DPI for digital printing can vary depending on the type of ink, the type of substrate being printed on, and the printing method to be used.
Using the wrong DPI for your designs can have negative effects on the quality of your t-shirt prints. A low DPI can result in blurry and pixelated prints, while a high DPI can cause the ink to bleed and create a messy design.
So, when it comes down to it all, it’s essential to choose the right DPI for your designs to ensure that your t-shirt prints look their absolute best (and you do, right?).

Photo Print Resolution Guide: Choosing the Right DPI for Your Designs
Ok, let’s talk about printing your own custom designs for your t-shirts.
Here is a photo print resolution guide to choosing the right DPI for your designs based on the type of design and custom t-shirt printing method:
1. Type of Design
The type of design you’re printing on your t-shirt can have a significant impact on the ideal DPI. Here are some general guidelines:
Text-based designs
If your design primarily consists of text, a DPI of 150-300 is typically sufficient. However, if your font has intricated details or is particularly small, you may want to consider using a higher DPI.
Graphic designs
For designs with graphics, you’ll want to consider the level of detail in the design. More detailed designs will require a higher DPI. The rule of thumb is to aim for a DPI of 300 or higher for intricate graphics.
Photographic designs
Photographs require a high level of detail, so you’ll want to use a DPI of at least 300 – or preferably higher.
2. Custom T-Shirt Printing Method
The printing method you choose for your custom t-shirts can also impact the ideal DPI. Here are some guidelines based on common printing methods:
Direct-to-Garment (DTG) Printing
DTG printing is a popular choice for custom t-shirts. This method can produce high-quality prints with a wide range of colours. For DTG printing, a DPI of at least 300 is recommended.
Screen Printing
Screen printing is another popular choice for custom t-shirts. This method can produce vibrant and consistent colours, and is ideal for large quantities with low colour artwork. For screen printing, vector artwork is required.
Heat Transfer Printing
Heat transfer printing is a method that involves transferring a design onto the t-shirt using heat. For this method, a DPI of at least 300 is recommended.
3. Other T-Shirt Printing Considerations
In addition to the type of design and printing method, there are a few other factors to consider when choosing the right DPI for your custom t-shirts:
- T-Shirt Material: The material of your t-shirt can impact the way your design looks. If you’re printing on a material that absorbs ink quickly, such as cotton, you may want to use a higher DPI to ensure that the design appears crisp and clear.
- Viewing Distance: The ideal DPI can also depend on how the t-shirt will be viewed. If the t-shirt is viewed from a distance, you may be able to get away with a lower DPI.
By considering these factors and following the DPI printing on clothing guidelines above, you can choose the right DPI for your custom t-shirt designs, resulting in high-quality, professional-looking prints.

How to determine the DPI of your image and adjust it for the best custom t-shirt printing results
It’s all in your hands, with the tech of today. Determining the DPI of your image is a simple process that can be done using photo editing software.
Once you’ve determined the DPI of your image, you can adjust it accordingly. If your design has a low DPI, you can increase it using photo editing software. Conversely, if your design has a high DPI, you can decrease it to ensure that the ink doesn’t bleed during printing.
Choosing the right DPI for your designs is a critical factor in achieving high-quality t-shirt prints.
