To achieve the best results from your photography, size matters. Using the correct image size can make sure your photos appear in a shape that best fits the subject.
Therefore, it’s worth knowing what size your photo will be before you take it. This way, you can make sure the aspect ratio you’re using reflects the size of the image and the subject of the photo - so you don’t have to crop out as much from your photo to make it fit.
When you’re designing for the web, it’s important to think about image sizes as it can affect site speed. If an original image is larger than the space it fills on a website, it will shrink to fit. However, your browser will still need to load the larger image.
If you have lots of large photos on a website, it can take longer for pages to load, which users might not be patient enough to hang around for. By resizing images so they fit the exact space they are supposed to, you can improve the site’s performance and user experience.
What is aspect ratio?
An aspect ratio refers to the ratio of an image’s width compared to its height. It essentially tells you what shape the photo is going to be.
For example, an aspect ratio of 1:1 means the width and height are the same, creating a square image. A ratio of 3:2 means the width is greater than the height, creating a rectangular image.
Common aspect ratio sizes.
1:1 aspect ratio.
Using a 1:1 aspect ratio means you’re shooting a square image, as both sides are the same width and height. It’s commonly used for things like social media profile photos.
3:2 aspect ratio.
Another common aspect ratio is 3:2, which is used across much of film and digital photography. This is the aspect ratio of original 35 mm film, which is why it’s so commonly used.
4:3 aspect ratio.
4:3 is the aspect ratio that some computer monitors, TVs and digital cameras use. This is the perfect aspect ratio to shoot photos or film in if you’re creating photos that will fill a screen.
16:9 aspect ratio.
A 16:9 ratio is more common on most computer monitors and modern wide-screen TVs. This is a slightly longer width than a 4:3 aspect ratio.
What are the standard image sizes for print?
When you’re designing for print, it’s important to know what the correct size is for the image you want to use. There’s nothing worse than printing work and realising the photo has become pixelated or misshapen. Discover the main print sizes and what they are appropriate for:
