Visuals are everything when it comes to social media. When it comes to Instagram, the size of your posts may make or break your brand’s online profile. We at Ecompapi, a full-service branding agency, have witnessed how pixel-perfect content can get people to interact with it, bring in traffic, and help create a brand’s identity. But Instagram changes all the time, so it’s not just helpful to know the current sizes—it’s imperative.
This 2025 new Instagram photo Size Guide will make sure that every post, story, and reel appears clear, professional, and on-brand, no matter if you run a small business, are an influencer, or run a creative firm.
Why Instagram Measurements Matter in 2025
It’s not just about aesthetics anymore.
Instagram being a highly view-centric platform by itself, the size of an image directly affects the engagement rates. Too heavy images? Details disappearing into crops? Higher than expected visual blur? Any of these puts out the wrong vibe and hits user experience hard.
Within the constraints of its own unique design, Instagram’s algorithm tends to favour content that fits right in. In other words, properly sized content stands out more for being shown, for being shared, and for being saved.
From our branding standpoint, we at Ecompapi are always pushing down the throat of our clients that creative content is not the end-all, but whichever format gets the best results. It is all down to even a few pixels for the credibility of a brand.

1. Instagram Post Size 2025 – Feed Posts That Pop
Here we go for the classics: Instagram feed posts.
Brands would often mix square, portrait, and landscape format to create some visual variety. But each has its own best measurement sets.
| Type | Instagram Post Dimensions (in pixels) | Aspect Ratio |
| Square | 1080 x 1080 | 1:1 |
| Portrait (Vertical) | 1080 x 1350 | 4:5 |
| Landscape (Horizontal) | 1080 x 566 | 1.91:1 |
Ecompapi Tip: Go vertical when you can. A portrait view takes up more screen space and stops an otherwise near-distracted scroll-door slide, especially when you have tow-thumb-stopping content for your brand.
2. Instagram Story Size 2025 – Maximise the Vertical Canvas
We can, therefore, concur that stories are still one of the most popular types of Instagram content. Getting the dimensions right is a must.
| Instagram Story Size | 1080 x 1920 pixels |
| Aspect Ratio | 9:16 |
Instagram stories are full-screen vertical content, and any straying from the right ratio might very well be stereotyped as odd cropping or a blur.
Ecompapi Tip: Try to keep a safe zone of 250px top and bottom to ensure text is never clipped by the profile icon or ‘Send Message’ box.
3. Instagram Reels Size 2025 – Go Full Frame
In 2025, Instagram Reels are really going to be the response to TikTok and one of the best platforms for visibility and reach.
| IG Reels Dimensions | 1080 x 1920 pixels |
| Aspect Ratio | 9:16 |
Reels have two viewing modes:
- On the Reels tab – full-screen (9:16)
- On the main feed – cropped a bit (4:05 shown in preview)
Ecompapi Tip: Keep all important text and CTA elements within the safe zone (1080 x 1350 px) to prevent these from being cut off in feed previews.
4. Instagram Carousel Posts – Consistency Is Key
Carousel posts will remain at the top of brand storytelling strategy chains in 2025. Up to 10 slides can be included, and each must match one another in format to offer a smooth swipe experience.
| Recommended Dimensions | 1080 x 1080 or 1080 x 1350 |
| Aspect Ratio | 1:1 or 4:5 |
Be it a stepwise guide, product reveal, or visual case study—carousels are your storytelling superpowers. However, mismatched slide dimensions can make the whole thing look unprofessional.
Ecompapi Tip: Maintain the same Instagram portrait size throughout the slides. Vertical carousels (1080 x 1350) convey a stronger visual impact.
5. Instagram Profile Picture – Brand Identity Starts Here
Your profile picture is small but mighty. It’s the first impression users get of your brand.
| Size | 320 x 320 pixels |
| Format | Square (1:1) |
Even though Instagram displays it as a round figure, make sure that your logo or image is centred to avoid getting cropped.
Ecompapi Tip: Upload at high resolution to future-proof visual quality; use the brand mark or icon for recognisability.
6. Instagram Ads – Optimise for Every Format
In 2025, advertisements on Instagram will be displayed on stories, feeds, explore, reels, and so forth; hence, each form requires different sizing.
Here’s a quick breakdown:
| Ad Placement | Size (in pixels) | Aspect Ratio |
| Feed Ad | 1080 x 1080 / 1080 x 1350 | 1:1 / 4:5 |
| Story Ad | 1080 x 1920 | 9:16 |
| Reels Ad | 1080 x 1920 | 9:16 |
Ecompapi Tip: Don’t just resize, redesign each ad, accordingly, based on platform behaviour and user experience. What works in feed might not work in Stories.

Bonus: Designing with Branding in Mind
The perfect Instagram dimensions are just the beginning. At Ecompapi, we say: Great design meets great branding.
How to align your Instagram visuals with the brand:
- Stick to a visual grid. Consistent colours, fonts, and filters.
- Always put mobile on top. Most users are mobile-interacting, so in essence, your layout should reflect this.
- Guard the negative space. Never cram-too much takes away from the visuals.
- Place the logo, but quietly. Brand subtly but intelligently.
Why this is important: Each pixel tells a story for the brand. If the sizing is right and the branding is strategically good, then an Instagram feed becomes your greatest marketing asset.
Final Thoughts: Future-Proof Your Content with the Right Dimensions
Instagram will be highly dynamic, competitive, and content-rich in the year 2O25. And, in this environment, precision translates to power.
Using correct dimensions of an Instagram post-whether a story, reel, carousel, or ad-will ensure that the content is clean, nice, and friendly with the algorithm.
At Ecompapi, we attain the details right-from pixels to positioning-so that the brand does not just show up on Instagram but stands out.
