What image size do I need?
It depends on how you intend to use the image. Each image page has sizing and dimensions listed. Here are a few additional guidelines across our image size options:
Small: good for mobile and most web uses including blogs, advertisements, and websites.
Medium: bigger web use (ex. full width background images).
Large: usable for almost all needs, such as full page prints or any type of web or digital usage.
When searching, you can use our filter tool to sort by size:
Where can I see what size an image is available in?
When you open a photo page, you can see the available image sizes to license to the right hand side of the image. In some cases a photo may only be available in a small size. If you require a certain image size for your projects, we recommend filtering your searches and collections by image size to ensure you are only seeing photos of the size that you require.
I downloaded a photo. Why is it not 300 dpi?
The DPI listed in the photo details is meant to demonstrate up to what size you could print the photo at that DPI. For example, let's say you downloaded the "Large" size for this photo:
You could print the photo at up to 10.8" x 8.1" at 300 DPI (or 45.33" x 34" at 72 DPI). If you need to change the DPI of your file, you can do so by either opening up the photo in:
Photoshop: Image > Image Size > Uncheck the "resample image" box > Change the DPI (resolution) to "300" instead of "72"
Preview (Mac): Tools > Adjust Size > Uncheck the "Resample image" box > Change the DPI (resolution) to "300" instead of "72"
More About Image Resolution:
As a general rule of thumb, photos that are over 3000 x 2000 PX and 10" x 8" are better if you have larger use cases - like this photo for example, which is 6016 x 4016 PX and 20" x 13.3".
It is important to note that once enlarged and printed, DPI will not be as high (aka the resolution is compromised). If you are comfortable editing a photo to create noise/grain that would help give the photo a better resolution!

Before you license a photo you can always download a comp so you can see what the photo will look like in your work before purchase. The "Get a Comp" feature is located bottom right hand corner of every photo on Twenty20 and you can download as many comps as you need!
