Image Quality: Why 300 DPI Matters and How to Check Yours
Here’s a conversation Print Lord has far too often: a client sends over a Canva design that looks absolutely perfect on their laptop. Clean layout, good colours, everything in the right place. Then we zoom in to check the images, and it’s like looking through frosted glass. Blurry, pixelated, completely unusable for print.
The client is baffled. “It looks fine on my screen,” they say. And they’re right. It does look fine on screen. But screen quality and print quality are two completely different beasts, and if you don’t understand the difference, you’re heading for an expensive disappointment.
This is where DPI comes in, and this is where most Canva users come unstuck. Let’s fix that.
What Is DPI and Why Does It Matter?
DPI stands for Dots Per Inch. It’s a measure of how much detail an image contains when it’s printed at a specific size. The more dots per inch, the sharper and clearer your image will be in print.
For screens, 72 DPI is perfectly adequate. Your laptop, phone, and tablet don’t need any more detail than that to display images crisply. But print is physical. It’s tangible. You can lean in close and examine it. And at 72 DPI, print looks awful, blurry, amateurish.
The industry standard for print is 300 DPI. At that resolution, images look sharp, professional, and exactly how you’d expect them to. Anything below 300 DPI starts to show problems, and anything below 150 DPI is frankly embarrassing.
Print Lord has reprinted countless jobs because clients didn’t realise their images were too low resolution. We’ve had to have difficult conversations about why that lovely photo they found online won’t work for their poster. And we’ve watched businesses waste money on print that looked amateur because nobody checked the image quality first.
You don’t have to be one of them.
The Difference Between 72 DPI and 300 DPI
Let’s make this practical. Imagine you’ve got a photo that’s 1000 pixels wide. At 72 DPI, that image can be printed at about 14 inches wide and still look acceptable on screen. But in print? It’ll look soft, blurry, lacking detail.
That same 1000 pixel image at 300 DPI can only be printed at about 3.3 inches wide and maintain sharpness. Go bigger than that and you’ll see the pixels. The image breaks down.
This is why Print Lord always checks image resolution before we send anything to print. It’s not about being picky. It’s about making sure your print doesn’t look like a cheap photocopy when it could look professional and sharp.
Screen resolution tricks you. Your laptop shows you a small version of the image, and it looks great. But when that image is blown up to print size, suddenly all the flaws appear. The detail that your screen didn’t need becomes glaringly obvious in print.
How to Check Image Quality in Canva
Canva makes this relatively straightforward, but you do need to know what to look for. Here’s how to check whether your images are print-ready:
Step 1: Click on the Image
Select the image you want to check in your Canva design. Look for any warning icons or quality indicators that Canva displays.
Step 2: Look for the Low Quality Warning
Canva will often show you a small warning icon if an image is low resolution. It usually appears in the corner of the image or in the toolbar when the image is selected. If you see this warning, that image needs replacing.
Step 3: Check Image Dimensions
Click on the image and look at the dimensions. If you’re printing an A4 flyer and your image is only 500 pixels wide, that’s going to be a problem. For an A4 print at 300 DPI, you need images that are at least 2480 pixels wide.
Step 4: Zoom In
Zoom your Canva design to 100% or higher and look closely at your images. If they look soft or pixelated at this magnification, they’ll look worse in print.
Print Lord’s rule of thumb: if you have any doubts about image quality, find a better image. It’s easier to replace a dodgy photo now than to reprint an entire job later.
What to Do About Low Resolution Images
So you’ve checked your Canva design and discovered some of your images are too low resolution. What now?
Option 1: Find Higher Resolution Versions
Go back to the source. If you downloaded the image from a website, check whether a larger version is available. If it’s your own photo, go back to the original file before it was compressed or resized.
Option 2: Use Stock Photo Sites
Canva has built-in access to stock photo libraries. Use the search function to find high-resolution alternatives. Look for images labelled as high quality or suitable for print.
Option 3: Replace, Don’t Resize
Do not try to fix a low-resolution image by making it smaller in your design and hoping that solves the problem. It might work, but often the image is already too far gone. Replace it with a properly high-resolution version.
Option 4: Ask Print Lord
If you’re not sure whether your images will work, send your design over before you commit to print. Print Lord checks every file, and we’ll tell you honestly if there’s a problem and what your options are.
What you absolutely cannot do is ignore the problem and hope for the best. Print Lord has seen that approach fail every single time.
Common Image Quality Mistakes Print Lord Has Seen
Let’s talk about the mistakes that cost people time and money, because Print Lord has caught every single one of these before they became expensive disasters:
Mistake 1: Using Images from Websites
Images on websites are optimised for screen, not print. They’re compressed, reduced in size, and usually 72 DPI. They look fine online, but they’re nearly always unusable for print. Always go back to the original source file.
Mistake 2: Screenshotting Instead of Downloading
Taking a screenshot of an image destroys its resolution. Even if the original image was high quality, the screenshot won’t be. Always download the actual image file.
Mistake 3: Stretching Small Images
If you take a small, low-resolution image and stretch it to fill a larger space in your design, you’re making the problem worse. The image doesn’t gain detail just because you’ve made it bigger. You’re just making the pixels more obvious.
Mistake 4: Ignoring Canva’s Warnings
Canva tells you when an image is low quality. Listen to it. Those warnings exist for a reason, and ignoring them leads to disappointing print.
Mistake 5: Assuming Print Will Look Like Screen
This is the big one. What looks acceptable on your laptop will not necessarily look acceptable in print. Print is less forgiving. Details matter. Resolution matters.
Print Lord’s job is to catch these mistakes before they cost you money. But your job is to understand what makes a print-ready image so you’re not setting yourself up for failure from the start.
Practical Steps to Verify Image Quality Before Sending to Print
Here’s your actionable checklist for making sure your images are print-ready:
- 1. **Check Every Image in Your Design**
Don’t assume they’re all fine. Check them individually, especially if you’ve pulled images from different sources.
- 2. **Look for Canva’s Quality Warnings**
If Canva flags an image as low quality, replace it. Don’t try to work around it.
- 3. **Zoom to 100% and Inspect**
If an image looks soft or pixelated when you zoom in, it’ll look worse in print.
- 4. **Verify Dimensions Against Print Size**
Make sure your images are large enough for the print size you’re planning. For A4 at 300 DPI, you need at least 2480 x 3508 pixels.
- 5. **Use High-Quality Sources**
Stock photo libraries, original photography, or professionally supplied images. Don’t scrape images from random websites.
- 6. **When in Doubt, Ask Print Lord**
We check every file anyway, but catching problems early saves you time and stress.
Image quality isn’t glamorous, but it’s the difference between print that looks professional and print that looks cheap. And in a world where your print represents your brand in a tangible, physical way, that difference matters.
Why This Matters to Print Lord
Print Lord’s reputation is built on delivering print that’s on brand and on time, every single time. That means we check everything before it goes to print, including image quality. We’ve caught thousands of low-resolution images over the years and saved our clients from expensive disappointments.

When you understand what makes an image print-ready, you make better choices. You pick better photos. You design with print in mind from the start. And the final product looks exactly how you imagined it, not like a poor-quality compromise.
That’s what Print Lord is here for. Not just to print what you send us, but to make sure what you send us is going to give you the result you actually want. We guard your brand as if it were our own, and that starts with honest advice about image quality before we waste your money printing something that won’t meet your standards.
