Common aspect ratios
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.

File Formats and File Size
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.

Where to get Stock Photos for your next Campaign
Whatever your next marketing project may be, there are plenty of stock image sources to find these standard picture sizes for marketing materials:
The StockPhotoSecrets Shop is the best source for small and medium-sized businesses to get quality stock imagery at a great price. You can get images at whatever size you need since Stock Photo Secrets doesn’t tie price to image size. You just pay for the download.
Furthermore, you can purchase either image packs or a subscription depending on how many images you need each month. Subscriptions will give you the most for your money, but image packs might be all you need if you don’t use stock images often. Check out the available pricing plans here.
Photocase is the best source available for authentic and candid stock photos for your projects. They have very high standards for the images they accept, so though their library is smaller, it is very high in quality.
