Store ratios, not just platform names
A 9:16 master can support several full-screen placements, while 4:5 and 3:4 need their own layout logic.

Social media image sizes 2027: the designer’s current-spec cheat sheet
Planning templates and campaigns for 2027? This guide starts with the latest platform guidance available now, then keeps the date visible so you know when the specs were last checked.
2027 planning guideBased on current platform guidance reviewed 27 September 2026. We’ll update this page when platform specifications or UI change.
Social media sizes to build into your 2027 templates
Use these as practical production masters, then check the platform-specific page for interface and cropping notes.
| Format | Dimensions | Ratio | Design note |
|---|---|---|---|
| Instagram feed | 1080 × 1440 px | 3:4 | Tallest current native feed-photo format. |
| Instagram Story / Reel | 1080 × 1920 px | 9:16 | Full-screen vertical canvas. |
| LinkedIn portrait post | 1080 × 1350 px | 4:5 | Practical tall organic-photo canvas within LinkedIn’s current ratio range. |
| TikTok video | 1080 × 1920 px | 9:16 | Practical full-screen master; TikTok recommends vertical and at least 720p. |
| Facebook feed | 1080 × 1350 px | 4:5 | Practical portrait feed canvas; square remains useful. |
| Facebook Story / Reel | 1080 × 1920 px | 9:16 | Full-screen vertical format. |
Three rules for a social template library that stays useful
Separate specs from UI
Correct pixels do not guarantee a believable mockup. The platform interface, safe zones and crop behaviour matter too.
Date every guide
Social platforms change. A visible review date is more useful than pretending a spec sheet is permanent.
What designers need to know
Why MockUp Buddy is publishing 2027 guides before January
Designers, social teams and agencies build next-year templates before the calendar changes. Publishing the 2027 guides now gives those teams something useful to plan against while being clear that the numbers are the latest current specifications, not predictions.
As platforms change, the pages can be updated without throwing away the search authority or the useful explanation around each format.
Preview it properly

Open MockUp BuddyFrequently asked questions
Are these definitely the final social media sizes for 2027?
No. They are a 2027 planning guide based on current platform guidance reviewed on 27 September 2026. The pages will be updated when platforms change.
Why publish a 2027 size guide in 2026?
Designers and social teams often build next-year template systems and campaign plans in advance. The guide is explicitly date-stamped so the timing is clear.
Which social media size should I design first?
Start with the placement that matters most to the campaign, then create intentional adaptations for the other ratios rather than relying on automatic cropping.
