Want to learn more? Here's Everything you need to know about creating custom t-shirt with GPTShirt.
Yes, absolutely. GPTShirt.ai offers custom t-shirts with no minimum order size. That makes it easy to create personalized apparel for yourself, a unique gift, or a small test batch before ordering in bulk.
We use premium Direct-to-Garment (DTG) printing, which utilizes water-based inks to print vibrant, detailed graphics directly into the fabric fibers. This method is superior for full-color designs and ensures your custom tee feels soft and breathable, unlike thick vinyl.
Our tees are made for premium comfort across all ages: Adult, Youth, and Toddler tees feature soft, lightweight Airlume combed and ring-spun cotton. This premium material gives every size a smooth feel, long-lasting quality, and comfortable stretch.
We provide an industry-leading selection of colors and a comprehensive size range covering Adult, Youth, and Toddler apparel. Available colors vary, but you can preview every option by launching our AI Designer tool.
For the most accurate fit, we highly recommend reviewing the detailed T-shirt size chart found on each product page. Our shirts have a modern retail fit, so measuring a favorite tee and comparing the length and chest width is the best way to determine your size.
To maintain the DTG print durability, always wash your garment inside out in cold or warm water. Use a gentle cycle and mild detergent. Tumble dry on low or, ideally, hang dry. Avoid using chlorine bleach or harsh cleaning agents.
Yes. Our easy-to-use design interface allows for customization on the front, back, or both sides of your custom T-shirt. You can apply designs to any available printable area on our youth and toddler sizes as well.
Shipping cost and delivery time depend on the method you choose at checkout. After you enter your shipping address, we show live rates and estimated delivery for each available option (such as standard and express, when offered). Production time is separate from transit time.
Absolutely. The GPTShirt AI is trained to generate high-resolution files and formats all text and graphics specifically for professional, vibrant DTG production. Your final custom print will be sharp and true to the preview.
Yes. Ordering custom t-shirts in bulk is simple. You can easily duplicate your finalized design across various quantities, colors, and sizes within a single order.
