You spent hours perfecting your design. It looks amazing on screen. Then you get the printed tee — and it's blurry.
This happens to a lot of brand owners, and the fix is simple once you know what to look for. This guide walks you through everything, step by step, with no technical jargon.
Section 1 — Why Does 300 DPI Matter?
DPI stands for Dots Per Inch — it's the number of ink dots a printer lays down in every inch of the final print. The higher the number, the sharper and more detailed the result.
Here's the problem: screens only need 72–96 DPI to look great. But printing needs 300 DPI minimum. An image that looks perfectly crisp on your laptop can come out blurry and pixelated on a t-shirt if it was only designed for screen use.
The most common scenario: you generate an image with an AI tool (like ChatGPT, Midjourney, or Canva's AI feature), it looks sharp on screen, but it's actually only 72 DPI — less than a quarter of what's needed for print.
Simple rule to remember: Your image needs to be at least 3000 pixels wide for a clean print on a standard t-shirt. If it's less than that, the print may come out soft or blurry.
Screenshot needed: A side-by-side comparison of a 300 DPI print (sharp) vs a 72 DPI print (blurry). Search Google for "300dpi vs 72dpi print comparison" or use an actual printed sample photo.
Section 2 — How to Check If Your Image Is Good Enough
You don't need any special software. The fastest way is to check the pixel dimensions of your image directly on your device.
On Windows
- Find your image file in File Explorer
- Right-click the image → select Properties
- Click the Details tab
- Look for Width — if it shows 3000 or higher, you're good to go
Screenshot needed: Windows right-click → Properties → Details tab, with the "Width" row circled or highlighted.
On Mac
- Click the image once to select it
- Press the Spacebar to open Quick Look
- The pixel dimensions are shown at the bottom of the preview window
- If the width is 3000px or more, you're good to go
Screenshot needed: Mac Quick Look preview window showing pixel dimensions at the bottom (e.g. 3000 × 3000).
On iPhone / Android
- Open the image in your Photos app
- Tap the info icon (i) or swipe up on the image
- Look for the dimensions listed under the photo details
Good news for phone photographers: Photos taken on modern iPhones and Android flagship phones are usually 4000px+ wide — they're already print-ready. No action needed.
Section 3 — My Image Doesn’t Meet the Requirement. What Now?
Don't worry — here are two easy paths depending on your situation.
Situation A: You Haven’t Started Designing Yet (Best Option)
If you're using Canva to create your design, this is the easiest fix — just set up your canvas at the right size from the beginning.
- Open Canva and click Create a design
- Select Custom size
- Enter 3000 × 3000 px
- Create your design on this canvas
- When done, click Share → Download → select PNG
That's it. Your file will have enough pixels for a sharp print — no DPI knowledge required.
Screenshot needed: Canva "Create a design" → Custom size screen, with 3000 × 3000 px typed in. Circle or highlight those two number fields.
Situation B: Your Design Is Already Done But the File Is Too Small
Use Adobe Express (free, no subscription needed, works in your browser) to resize it.
- Go to adobe.com/express
- Click Resize image
- Upload your file
- Set the width to 3000 pixels
- Download as PNG
Screenshot needed: Adobe Express Resize Image page, showing the width input field set to 3000.
⚠️ Important: Resizing a very small image (like 500px) to 3000px won’t magically create sharp detail — it just makes a blurry image bigger. For best results, start with a file that’s at least 1500px wide before resizing. If your AI-generated image is too small, try regenerating it at a higher resolution in your AI tool first.
Section 4 — Quick Checklist Before You Upload
Run through this before uploading your design to Storiginator:
- ✅ My image is at least 3000 pixels wide
- ✅ The file format is PNG (with transparent background if possible)
- ✅ The design looks sharp at full size when zoomed in on screen
- ✅ If I used an AI tool to generate the image, I’ve checked the actual pixel dimensions — not just how it looks on screen
Still unsure? Send your file to us before placing your order and we'll check it for you.
