Frequently Asked Questions
A. Dimensions & Ratios
01What is 1080×1350?
1080×1350 is a 4:5 portrait ratio — the recommended size for Instagram and Facebook feed posts. It uses more vertical screen real estate on mobile, which typically yields higher engagement than the 1080×1080 square.
02What does the 1.91:1 aspect ratio mean?
An aspect ratio where width is 1.91× the height (e.g., 1200×630). It is the canonical dimension for link-preview cards on Facebook, LinkedIn, and X — the image shown when you share an article URL.
039:16 vs 4:5 — which should I use?
9:16 (1080×1920) is full-screen vertical — for Stories, Reels, TikTok, and YouTube Shorts. 4:5 (1080×1350) is portrait but not full-screen — for Feed posts that coexist with caption text. Use 9:16 for immersive content, 4:5 for evergreen feed posts.
B. Quality & Common Issues
04Why does my image look blurry on Facebook?
The most common reason is uploading too small — Facebook compresses heavily but never upscales. Always upload at the recommended pixel size (1080×1080 for posts, 1200×630 for link previews) and save as JPEG quality 85% or higher.
05What is the best Instagram post size?
1080×1350 (4:5 portrait). It occupies more vertical space than the 1080×1080 square, which generally translates to higher reach on mobile feeds where users scroll vertically.
C. Per-Platform Specifics
06TikTok video dimensions?
1080×1920 (9:16 vertical) — full-screen on mobile. Use the same dimension for the custom cover/thumbnail. Always shoot vertical; horizontal video gets letterboxed.
07LinkedIn cover photo size?
Personal profile cover: 1584×396 (4:1). Company page cover: 1128×191 (~5.91:1). Keep important content within the central 60% — the edges may be cropped on mobile.
08YouTube thumbnail size?
1280×720 (16:9), JPEG/PNG/GIF under 2 MB. The same image is also used for Shorts thumbnails when displayed on the channel grid; for Shorts native playback, the player crops to 9:16.
Tip: Bookmark this page. Pixel sizes change rarely, but every new platform feature ships its own dimension — check back when launching new content formats.
Best Practices สำหรับนักการตลาด ไทย
Always design with Mobile-First in mind.
Over 95% of users in Thailand access social media through mobile devices, so content should be designed for mobile screens first, and then adapted for desktop.
2. Always use high resolution.
Even though the platform compresses files, uploading high-resolution images (1080p and above) results in better quality after compression.
3. Prepare a Safe Zone for messages.
For Stories and Reels, a Safe Zone of 250px should be maintained from the top and bottom to prevent text from being obscured by the app's UI.
4. Testing on real devices
Don't rely solely on the Preview on your computer; it's important to test on a real mobile device as colors and sharpness may vary.
