If you’re a business owner, marketer, or content creator, you know that social media never sits still. Just when you’ve finally nailed the right Instagram layout or figured out the best way to design your Reels, the platform changes something.
And this time, it’s your Instagram post size that’s shifted… again.
Instagram has just updated its feed post dimensions, and while the change might seem minor, it has implications for how your content looks and performs. Here’s a simple breakdown of what’s changed, why it matters, and what you should do right now to keep your brand looking polished and professional online.
What’s Changed in 2025
In 2025, Instagram officially expanded the maximum height of feed posts to 1080 × 1440 pixels.
Previously, the tallest feed post size was 1080 × 1350 pixels — a format that’s been standard for years. The new 1080 × 1440 px update brings feed posts closer to the full-screen format of Reels (1080 × 1920 px), allowing creators and brands to use a slightly taller canvas.
This means your posts can now take up more vertical space on the screen when people are scrolling their feed — a change that might sound small but could make a noticeable difference in engagement.
Why It Matters
More Screen Real Estate
The taller your post, the more room it takes up on the screen and the more attention it grabs.
That extra 90 pixels of height can mean your audience spends a split-second longer looking at your content, which can lead to higher engagement over time.
Think of it like a digital billboard: the bigger your visual, the more chance it has to stand out.
Alignment With Reels Format
Instagram’s ongoing goal is to make the platform more consistent visually. By allowing taller static posts, the app is moving closer to the Reels aspect ratio -9:16- which already dominates users’ screens.
This consistency helps your profile grid, feed previews, and Reels tab feel more cohesive, especially if your brand regularly posts video content.
Scheduling Tools Aren’t Quite Ready Yet
Here’s the catch: while Instagram supports 1080 × 1440 px uploads, most third-party scheduling tools haven’t caught up yet.
Platforms like Meta Business Suite, Later, and Canva Scheduler still optimise feed posts for 1080 × 1350 px.
That means if you upload taller posts through these tools, they may automatically crop or resize your images, which can throw off your composition or cut off important text.
So what does this mean for your social media strategy?
✅ Stick With 1080 × 1350 px (For Now)
Until scheduling tools and in-app previews fully support 1080 × 1440 px, your safest bet is to keep designing for 1080 × 1350 px.
The difference is visually minimal, only about 6.6% taller, so you won’t be missing out on much. Sticking with the existing format ensures your posts display correctly across every device and scheduling platform.
✅ Keep Your Designs Centred
If you’re keen to experiment with the new size, make sure the main subject and text of your design stay well within the centre 1350 px height zone. That way, even if a tool crops the post, your key content won’t be cut off.
✅ Test Engagement
When Instagram makes a change, it’s always worth testing. Try posting one or two images in the new size directly through the app (not via a scheduler) and see if your engagement metrics, likes, saves, or reach shift.
Every audience behaves differently, and what works for one account might not for another.
✅ Communicate With Your Design Team
Make sure your designer is aware of this update. It’s easy for a post to look “off” if it’s been cropped incorrectly, so clear communication around sizing is key.

Why Staying Updated Matters
Social media moves fast, sometimes faster than your content calendar. Small changes like this one can easily go unnoticed until your images start cropping strangely or your engagement drops for no clear reason.
That’s where having the support of a dedicated social media management team in Auckland makes all the difference.
A Few Reasons to Stay Ahead:
- Consistency Builds Trust: When your visuals look crisp and properly sized, your brand feels professional and reliable.
- Algorithm Advantage: Instagram tends to favour content that’s optimised for its newest formats, especially when those formats align with user behaviour (e.g. vertical video or taller imagery).
- Time Efficiency: Instead of troubleshooting why your post looks odd, you can focus on strategy, storytelling, and engagement, the things that really move the needle.
- Platform Expertise: A good marketing agency monitors these updates for you and makes sure your brand adapts quickly without losing quality or cohesion.
Our Takeaway: Don’t Panic, Stay Smart
Yes — Instagram post sizes just changed (again). But no, you don’t need to overhaul your entire content plan overnight.
The truth is, the update is relatively minor, and your current 1080 × 1350 px designs will continue to perform perfectly well for now.
So keep calm, carry on creating, and save the new size for testing once your scheduling tools catch up.
And if you want someone else to keep an eye on these updates for you, while making sure every post, Reel, and ad looks its best, that’s where we come in.
