Image resolution is a BIG THING when it comes to print (paper, fabric, whatever).

In this article, I'll do my best to explain a complicated subject in the simplest terms I can think of.

What image format do you accept?

We accept both JPG and PNG files.

Digital images are made of pixels

When you look at an image's properties, one of the first things you'll see is its dimensions. It can look something like this:

In this case, this is telling me that we are looking at an image of 3780 pixels wide by 3780 pixels high.

What are megapixels?

One megapixel = 1 million pixels.

Take the previous image for example: 3780x3780 = 14.3 million pixels.

Or 14.3 megapixels

Or simply 14.3 MP

Is resolution important?

No, not really. Let's check: Resolution tells you how many pixels an image has in square inches (DPI stands for Dots Per Inch).

Let's take our 3780x3780 image as an example.

Most printed magazines (the glossy ones in the stand at your nearest pharmacy or bookstore) require a 300 DPI resolution.

  • At 300 DPI, this image is 12.6 inches wide by 12.6 inches high. (3780 pixels / 300 DPI = 12.6 inches)

  • Your computer screen, however, is likely at 72 DPI. This means it's almost 53 inches wide on your screen!!

  • We print at 120 DPI, which means this artwork is 32 inches wide for our fabrics;

Whether it's at 300, 120, or 72 DPI, it contains the same number of pixels. A tiny image of 500 pixels by 500 pixels is still tiny even at 300 DPI. It contains the same data.

Considering the situation, requiring a certain resolution or DPI makes no sense.

What we REALLY want to know is how many pixels your image has. We count them by the millions. Hence; megapixels.

What megapixels does Le Galeriste require?

We've discovered over the years that 6 MP images look great almost 100% of the time. We've set it as the minimum.

So the quick answer would be: 6 megapixels

But the long answer is more complicated...

It takes a lot of pixels for an image to look perfect on a physical print!

We print at 120 dpi (dots per inch).

That means a 65-inch-long scarf would require an image to be 7800 pixels high (65 * 120) for the product resolution to be ABSOLUTELY PERFECT. And since the scarf is about 20" wide, that means it would also need to be 2400 pixels wide (120 * 20). For a total image of 2400 x 7800 or a whopping 18.7 MP.

Almost no one has such images. But we've discovered that 6MP does the trick on almost 100% of products over time.

Please ensure that your artwork is a maximum of 20MB and that you do not include any special characters in your artwork title when submitting.

Since we don't all have the luxury of working with professional photographers. Here's a great little video on how to take amazing pictures with nothing but a phone and the light of day. Again; not PERFECT. But well above "good enough".
