Understanding standard photo sizes and different aspect ratios – and what each size and ratio is commonly used for – will help you pick the best stock photos for your marketing materials.
In this guide, we’ll discuss common aspect ratios, the standard photo sizes for both web and print materials, and where to get stock images in the right size – like from the Stock Photo Secrets Shop – so you have the proper resolution before publishing or printing.

Aspect ratios are the proportional relationship of width to height in an image. For example, a 6 × 4 image has an aspect ratio of 3:2, because, for every 3 units of width, there are 2 units of height.

Image aspect ratios do not refer to a specific measurement, like inches or centimeters. They just refer to how high the image is compared to how wide it is these common sizes reflect:
1:1 ratio – perfect square format; used for social media, most commonly for Instagram posts and Facebook profile photos, and other mobile apps
3:2 ratio – rectangle; used for print photography (usually on photo paper) and common picture frame sizes
4:3 ratio – rectangle; used for television, camera, and desktop computer screens
16:9 ratio – wide rectangle; widescreen formats are used for video, slides, widescreen televisions, and most social media cover images. This is equivalent to a 1920 x 1080 aspect ratio, super popular as ultra HD resolution for video content.
Selecting images in the correct aspect ratio for the medium you intend them to be viewed in, ensures you will get a full-screen display at high definition, which is absolutely desirable. All the more when you will be working with a responsive design that has to adapt to multiple screens, like newsletter images. You can achieve this by getting images whose original aspect ratio matches your needs, or otherwise resizing them according to the preset dimension before uploading them to the final medium.
Standard photo sizes for web: Facebook, Instagram, …
Here’s a guide to standard sizes for social media images and other popular platforms:
Keep in mind there is a simple way to ensure your visuals are the right dimension for social media channels: you can use social media graphic templates which are predesigned and adjusted for each platform!
Twitch profile picture: 1600 x 1600 pixels; a 1:1 aspect ratio
Twitch banner image: 1920 x 480 pixels; a 4:1 aspect ratio

JPG/JPEG, PNG, TIFF… File format might seem irrelevant if you don't know much about digital imagery and graphic design. But it can make a difference in terms of image quality, which also affects image size for both digital viewing and printing. The level of detail an image in JPEG can have is a lot less than that of a TIFF picture, for example.
File format can be especially relevant when it comes to file size, which has a direct impact when using images on the web: how big an image file size is determines how fast –or slow– said image will load on a web page, as well as much space it'll occupy in your storage (local or cloud-based), among other considerations. And as a rule of thumb, the highest resolution images also have the largest file sizes. TIFF files, which preserve a lot of image details, are also much bigger than JPEG.
For digital use, the ideal format is one that offers the highest pixel count with the smallest file size. Webp is one such format, as it can store the image quality than JPEG, in files that are 25 to 35% smaller. Plus, converting from Webp to JPG and vice versa can be done very easily and within seconds, thanks to multiple web-based and software tools that handle this.
Using Webp files is one easy way to optimize your images for using on the web.
How to optimize images for web
If digital images aren’t optimized for the web, they’ll slow down the loading speed of your site. The longer your site takes to load, the more likely potential clients or customers are to click away before it’s done. Unoptimized images can mean lost business.
There’s a lot that goes into image optimization, but here are three very simple, photo editing beginner tips:
Don’t use the largest picture size. High-resolution, extra-large images take up space, which is unnecessary for the web. Resize your file without losing image quality with this tool from TinyPNG. There are also very good AI photo tools to help with this.
Name your image descriptively. You may be tempted to leave an image named a string of letters and numbers, but that won’t help your webpage. Instead, change the name to reflect what’s in the photo.
Take the below image, for example:

Naming it, “Tan_tote_bag_mockup.jpg” will be far more useful to your website’s optimization than leaving it “DSC20194.jpg.”
Use functional images. Try to only use images that are functional to your content, rather than just decorative ones.
A great, simple, and effective tool to turn your image into the perfect size for your intentions, is Canva Magic Resize. This feature from Canva lets you set a new dimension for your image, be it custom size or any of their preset dimensions for popular uses (think Facebook, Instagram, blog headers…), and automatically resizes it in one click, preserving image quality.

Standard print sizes
Print marketing materials are useful for local marketing. If you have a brick-and-mortar store or are promoting an event, these are the standard print picture sizes you’ll need to create printable marketing materials:
Once again, you can simplify the dimensions part of a design by using printable templates predesigned for your intended use!
Whatever your next marketing project may be, there are plenty of stock image sources to find these standard picture sizes for marketing materials:

Subscriptions run between $70 and $399 per month, depending on how many downloads you need.

I’m a long time pro photographer who used to shoot on Kodachrome with my Nikon, so no problems there. I’m now planning on sending digital images to stock photo agencies, but have no clue as to what size to save my files at. I get different answers everywhere I ask. My jpegs come out of the camera sized at 6000×4000. So, what to resize them at? And does dpi count?
Hi Michael, each agency has its own submission guidelines which include resolution requirements, where what matters the most is to meet the minimum size required for high res download. The minimum is usually 4 megapixels (mp) which translates into 2000×2000 px, but the industry standard of desirable size is around 15 mp. Your files at 6000×4000 are 24 mp so, more than okay to submit.
A good practice to determine image size is to zoom them into 100% and check that the edges and details of the main subjects are perfectly sharp. If there’s any softness at 100% zoom, then consider reducing the dimension some.
DPI doesn’t factor in, all agencies care about is pixel count.
