What DPI Do You Need for Printing? (And Why Your File Says 72)

"Your file is too low resolution" is one of the most frustrating emails an artist can get. The artwork looks sharp on your screen, your app says it's fine, and now you're being told it won't print well. Most of the time, the problem isn't your artwork. It's a confusing number called DPI that almost nobody explains clearly.

This guide explains what DPI actually means, how to check your file in a few seconds, how to set up your canvas correctly from the start in the most popular art apps, and what to do if your file is already too small.

The Short Answer

"At the final print size" is the part that matters. A file that's 300 DPI at 4×6 inches is not 300 DPI at 16×20. Stretch the same pixels across a bigger sheet of paper and each one gets bigger.

DPI Is a Label. Pixels Are What Matter.

This is the single biggest source of confusion, so it's worth getting clear on.

A digital image is made of pixels: a grid of tiny colored squares. A file that's 3,000 pixels wide has 3,000 squares across, no matter what DPI label is attached to it.

DPI (dots per inch), also called PPI (pixels per inch), is an instruction that tells a printer how many pixels to fit into each inch of paper. The pixels themselves don't change

That means:

• Changing 72 to 300 in a settings box doesn't add detail. If you change the label without adding pixels, you get the same image printed smaller, not a sharper one.
• A file labeled 72 DPI can still be perfect for print. A 3,600 × 5,400 pixel image labeled 72 DPI prints a beautiful 12×18 at 300 DPI. The label is wrong, but the pixels are all there.
• The only number that really matters is the pixel count. Divide the pixels by 300, and that's the largest size you can print at full quality.

Why Your File Says 72 DPI

Phones, screenshots, web downloads, social media images, and many export settings label files as 72 DPI by default. It's a leftover standard from early computer screens and has nothing to do with print quality.

When you see 72 DPI, don't panic. Check the pixel dimensions instead. If there are enough pixels for your print size, the file is fine, and we can print it as-is. If there aren't, that's when you have a real resolution problem.

How to Check Your File's Real Resolution

Find the pixel dimensions, divide each by 300, and you have your maximum print size.

On a Computer

• Windows: Right-click the file → Properties → Details tab → look for Dimensions.
• Mac: Open the file in Preview → Tools → Show Inspector. Or right-click in Finder → Get Info → More Info.

On a Phone

• iPhone: Open the photo in Photos and tap the ⓘ button. The dimensions appear under the camera details.
• Android (Google Photos): Open the photo, swipe up or tap the three-dot menu, and look for the resolution under details.

In Photoshop: See Your True Print Size

Go to Image → Image Size, uncheck Resample, and type 300 into the Resolution box. Photoshop will show you exactly how large the file prints at 300 DPI without changing a single pixel. This is the fastest way to see your real maximum print size.

What Common Images Can Actually Print

Here's how big some everyday image sizes print at 300 DPI. Many resolution problems come from files in this list.

Notice the first three. Images made for screens, including most AI generators and the default Procreate canvas, simply don't have enough pixels for large prints.

Pixels Needed for Popular Print Sizes

Smaller sizes include our required 0.125" bleed on every side. Large-format sizes don't need extra trim area. Full specs for every size are on our Art Specs page.

All sizes at 300 DPI. Need another size? See our guide to converting inches to pixels and centimeters.

How to Start Every Project at 300 DPI

The easiest way to avoid resolution problems is to never create them. Set your canvas to your final print size at 300 DPI before you draw a single line. Here's how in the most popular apps.

Tip: If you'll sell the same piece in several sizes, set up your canvas for the largest size you plan to offer. A big file always prints well small, but a small file never prints well big.

Procreate

1. In the Gallery, tap +, then tap the new custom canvas icon in the top-right corner of the menu.
2. Under Dimensions, change the units to inches.
3. Enter your print width and height (add 0.25" to each for bleed on smaller prints, such as 8.25 × 10.25 for an 8×10).
4. Set DPI to 300, name the canvas, and tap Create.

Check an existing canvas: Actions (wrench icon) → Canvas → Canvas information.

Procreate limits the number of layers you create based on canvas size and your iPad's memory. If a large print leaves you too few layers, merge layers as you go or work in sections. Don't drop the DPI.

Adobe Photoshop

1. Go to File → New.
2. Set the units to Inches and enter your width and height, including bleed for smaller prints.
3. Set Resolution to 300 Pixels/Inch.
4. Click Create.

Check an existing file: Image → Image Size. Uncheck Resample before changing anything so you don't alter the pixels.

Clip Studio Paint

1. Go to File → New and choose Illustration.
2. Change the unit to in and enter your width and height.
3. Set Resolution to 300.
4. Click OK.

Check an existing file: Edit → Change Image Resolution.

Adobe Illustrator

Vector artwork is made of shapes, not pixels, so it stays sharp at any size. But two things in Illustrator still depend on resolution:

• Effects like drop shadows, blurs, and textures. Go to Effect → Document Raster Effects Settings and choose High (300 ppi).
• Placed photos or raster images. Check them in the Links panel, which shows each image's effective PPI at the size you've placed it. Scaling an image up in Illustrator lowers its effective PPI.

Affinity

1. Go to File → New.
2. Set Document units to Inches and enter your width and height.
3. Set DPI to 300.
4. Click Create.

Check an existing file: Document → Resize Document.

Krita

1. Go to File → New and choose Custom Document.
2. Set Resolution to 300 pixels-per-inch.
3. Change the width and height units to Inches and enter your print size.
4. Click Create.

Check an existing file: Image → Scale Image to New Size shows the current dimensions and resolution. Click Cancel when you're done.

Canva

Canva doesn't have a DPI setting. You control print quality by designing at your print size and exporting correctly.

1. Click Create a design → Custom size, change the units to in, and enter your print size.
2. Turn on bleed with File → Settings → Show print bleed.
3. When you're done, click Share → Download and choose PDF Print, which exports at 300 DPI.

Canva can't add detail to the photos you upload. If you place a small image and stretch it across the page, it will still print soft. Use the largest version of every photo you have. See our guide on designing 11×17 in Canva for a full walkthrough.

"But It Looked Fine on My Screen"

Screens are forgiving. Most monitors and phones display around 100–150 pixels per inch. They also shrink your image to fit the display. A file that looks crisp on a laptop may be displaying only a fraction of its pixels at a time.

Paper is not forgiving. At 300 DPI, every pixel is printed at its true size, and anything soft, jagged, or blocky shows. To preview what print will reveal, zoom your file to 100% (actual pixels). That's much closer to what the print will look like than the zoomed-out view.

Why Very Large Banners Are the Only Exception

Viewing distance changes how much resolution you need. People pick up art prints, posters, and cards and look at them from arm's length or closer, so they need the full 300 DPI to look crisp. Smaller banners on a table or a booth wall get the same close look, so they need 300 DPI too.

Very large banners are different. They're read from across a room, a convention hall, or a parking lot, where nobody can see fine detail. At that distance, 200 DPI at full size looks just as sharp. It also keeps file sizes manageable: a 3×6 foot banner at 300 DPI would be over 230 megapixels, which many apps and computers struggle to handle.

Large posters are not banners. A 24×36 poster still gets hung on a wall and looked at up close, so it needs 300 DPI like any other print.

My File Is Too Small. Now What?

Try these fixes in order, starting with the one that gives the best result.

1. Go back to the source. If you exported a smaller version, re-export from the original file at full size. Check your export settings for a scale or quality option that may be shrinking your art.
2. Find the original photo. Images sent via text messages, email, and social media are often compressed. The original on your camera or phone is usually much larger.
3. Print smaller. If your file prints beautifully at 8×10 but not 16×20, an 8×10 may be the right product for this piece.
4. Rescan or reshoot the original. For traditional artwork, capture it again at a higher resolution. Our guide to scanning and photographing artwork walks you through it.
5. Use AI upscaling. Modern upscaling tools can recover surprising detail, especially for illustrations and clean digital art. We can use Topaz AI to fix low-resolution files (we always ask for permission first).

What doesn't work: changing the DPI number, or resizing in a basic editor without a dedicated upscaler. Both leave you with a bigger file that's just as soft.

What Happens When You Send Us a Low-Resolution File

A real person on our team checks every file before it prints. If your artwork doesn't have enough pixels for the size you ordered, we'll email you before anything goes to press. Depending on the file, we'll suggest a better print size, ask for a larger version, or offer to upscale it. You'll always see and approve the result first. Nothing prints until you're confident with the final print quality.

Low Resolution? We Can Help

If your file doesn't have enough pixels for the size you ordered, we won't print it. A real person on our team will email you with your options before anything goes to press. You can send a larger file, choose a smaller print size, or let us fix the resolution.

Frequently Asked Questions

What DPI do I need for printing?

300 DPI at the final print size for everything we print, including art prints, posters, cards, booklets, and most banners. Very large banners (around 3×6 feet and up) can drop to 200 DPI because they're viewed from across a room.

Is 72 DPI bad for printing?

Not necessarily. 72 DPI is often just a default label. What matters is the pixel count. Divide your pixel dimensions by 300 to see how large the file can actually print.

What's the difference between DPI and PPI?

Technically, PPI (pixels per inch) describes a digital file and DPI (dots per inch) describes ink on paper. In everyday use, including most software and print shops, the terms mean the same thing.

Can I just change my file from 72 to 300 DPI?

Changing the number alone doesn't add detail. If you resample the file to add pixels, it gets bigger but not sharper. To get a truly sharper file, re-export from your source, start with a larger canvas, or use a dedicated AI upscaler.

What canvas size should I use in Procreate for prints?

Set the canvas to the largest size you plan to sell, in inches, at 300 DPI. For an 11×17 print, that's 11.25 × 17.25 inches with bleed, or 3,375 × 5,175 pixels.

Can you print an image I downloaded from Instagram?

Instagram images are about 1,080 pixels wide, which is only enough for a print around 3.6 inches wide at full quality. Use the original file instead.

Do vector files need to be 300 DPI?

Vector shapes and text print sharp at any size. Any photos, textures, or effects inside the vector file still need to be 300 DPI at the size they're placed.
