Instagram Image Size
Not to be distracted by dozens of rules, your first task is to decide on the type of content to post. Instagram welcomes numerous formats, including photo and video posts, stories and reels, each of them unique in its own way.
The ideal Instagram post varies in size from 1080 × 608 pixels to 1080 × 1350 pixels. Profile pictures should be 320 × 320 pixels. The recommended size of the stories and reels is 1080 × 1920 px (9:16 ratio), which takes up the phone’s entire screen.
Instagram profile grids now display posts in a tighter vertical preview, which means parts of your image can get cropped. To avoid losing key details, avoid placing critical content near the outer edges (top, bottom, or sides). When designing at 1080 × 1350 pixels, keep essential elements within roughly the central 1080 × 1080 pixels area.
Threads Image Size
Threads supports flexible image formats, but it’s optimized for mobile-first, vertical viewing. The most reliable format is 1080 × 1350 pixels for feed posts, as it takes up more screen space and performs well visually. Square images (1:1) are still supported, while taller images (up to 9:16) may appear slightly cropped in previews. For best results, keep important text and visuals centered, avoiding the very top and bottom edges where captions and interface elements may overlap.
TikTok Dimensions
Unlike Instagram, which combines different sources of information, TikTok is famous for short 15-second clips; however, it now allows uploads of up to 3 minutes. They have the same full screen size as Instagram stories and reels: 1080 × 1920 pixels. As for the profile photo, 200 × 200 pixels is sufficient.
X Image Sizes
The recommended size for X profile images is 400 × 400 pixels. Header images should be 1500 × 500 pixels. As for post dimensions, the minimum size is 600 × 335 pixels, but feel free to expand this parameter; then your files will be better optimized for end users in their full version; however, remember to stick to a 16:9 aspect ratio. The maximum image file size for X posts is 15 megabytes.
YouTube Dimensions
This is where enthusiasts can reveal their individual creativity. This platform supports different video quality standards, but the higher, the better. For those who want to stay on the safe side choosing their channel branding, the minimum range to reach is 1546 × 423 pixels. Video thumbnails should have a resolution of 1280 × 720 pixels (with a minimum width of 640 pixels). The ideal channel profile picture is 800 × 800 pixels.
YouTube Shorts should be treated as a completely separate format from standard YouTube videos. While traditional uploads prioritize landscape (16:9) viewing and custom thumbnails, Shorts are built for full-screen vertical viewing (9:16) and rely heavily on in-feed discovery rather than thumbnail clicks.
Although Shorts don’t use thumbnails in the same way as standard videos, you can select a frame from the video to act as a de facto thumbnail in some contexts (e.g., channel pages). Make sure it’s clean, readable, and visually compelling.
Facebook Image Sizes
Depending on how you would like to operate the target image, tips will differ. For vertical portraits, the perfect match size is 1080 × 1350 pixels. In the case of sharing files via links or posting landscape images, the recommended dimensions are 1200 × 628 pixels. Profile pictures display at 170 × 170 pixels on desktops and 128 × 128 pixels on smartphones. Page's cover photos display at 820 pixels wide × 312 pixels tall on computers and 640 pixels wide × 360 pixels tall on smartphones. Facebook stories should be 1080 × 1920 pixels.
As of 2026, Facebook increasingly favor 1080 × 1350 pixels feed posts. This format is highly recommended for mobile, as it maximizes screen space and increases engagement compared to square images.
LinkedIn Image Sizes
The ideal profile picture size is 400 × 400 pixels (300 × 300 for company and group logos). Banners and background photos should be 1584 × 396 pixels (1128 × 191 for company pages, 1200 × 300 for events and 1536 × 768 for group pages). The optimum dimensions for post images are 1080 x 1080 and 1920 x 1080.
LinkedIn Carousel allow up to 10 swipeable, square (1:1) image cards, recommended size is 1080 × 1080 pixels in JPG or PNG format (max 10 MB per card). They require 2–10 cards, a 255-character max intro text, and 45-character max headlines per card.
