The ideal size of background images for web pages best suited for a desktop with a resolution of 1920 x 1080 px is 1600x900px. For the average photos, file sizes around 300 kb should be targeted, with some images spiking as high as 800 kb or as low as 100kb depending on level of detail, contrast and color in each photo.
Mobile Gallery apps enable you to create personalized gallery apps for your clients to install on their mobiles. The recommended image size for mobile galleries is 640 pixels in width with any height. In the Pixpa studio, for the gifs that are added, both width and height should be less than 2560px, and the frames in the gif should not exceed 60.
Image compression helps find the right balance between image quality and file size that affects the loading speed of a website. Uploading unnecessarily large or unoptimized images will not only negatively impact user experience due to longer load times but can also negatively affect SEO.
When displayed on Messenger, an image can vary from 1:2 to 2:1 aspect ratio (width:height). As a general guideline for images:
- Background images: 1920 x 1080 pixels (16:9 aspect ratio)
- Full-width images: At least 1400 pixels wide
- Half-width images: At least 700 pixels wide
- 1⁄3 width images: At least 480 pixels wide
- 1⁄4 width images: At least 360 pixels wide
- Small icons and logos: At least 100 pixels wide
- Gallery images: Any size
| Website Image Type | Image Dimensions (W x H) | Image Aspect Ratio |
|---|---|---|
| Background Image | 1920 x 1080 pixels | 16:9 |
1600px by 900px provides us with a 16:9 width-to-height ratio that works well for Facebook and Twitter, while the "padding" on each side of the image ensures the subject of the photo is not on the very edge, which also works for LinkedIn.
For Instagram, the ideal width is 1,080 pixels. If your image is less than 320 pixels wide, Instagram will enlarge it and it might look pixelated. The ideal size for an Instagram image is 1,200 pixels wide by 675 pixels tall (16:9 aspect ratio). The minimum size is 600 pixels wide by 335 pixels tall, but larger images will look better when followers click to expand the image. In terms of pixels per inch (ppi), the image should be at least 72.
