In this comprehensive guide, we’ll break down everything you need to know about the latest Instagram post dimensions for 2024 so that your content shows up perfectly—every time. Let’s dive in and get your feed looking professional and polished.

Why Correct Instagram Post Dimensions Matter in 2025

Instagram is a visually driven platform, and first impressions are everything. Using the correct dimensions isn’t just about aesthetics—it’s about:

Ensuring your visuals don’t get cropped or distorted
Maximizing engagement with clear, eye-catching content
Maintaining a consistent and professional brand appearance

Platforms like Instagram update their specifications frequently, which makes it essential to stay informed of the latest Instagram post dimensions.

Instagram Post Dimensions: The Basics

There are several types of Instagram posts, and each has its own ideal size. Let’s explore the most common types one by one.

1. Standard Instagram Feed Post Dimensions

Instagram feed posts can be square, portrait, or landscape. Here are the recommended sizes:

Square Post: 1080 x 1080 pixels (1:1 aspect ratio)
Portrait Post: 1080 x 1350 pixels (4:5 aspect ratio)
Landscape Post: 1080 x 566 pixels (1.91:1 aspect ratio)

Pro Tip: For maximum impact, go with a portrait post. It takes up more screen space and often leads to higher engagement.

2. Instagram Stories Dimensions

With over 500 million users engaging with Stories daily, optimizing for Stories is crucial.

Dimensions: 1080 x 1920 pixels
Aspect Ratio: 9:16
File Formats: JPG, PNG, MP4, MOV

Make sure to leave room at the top and bottom of your design for your profile info and call-to-action buttons like “Swipe Up” or “Link.”

3. Instagram Reels Dimensions

Instagram Reels has exploded in popularity, and the sizes mirror those of Stories:

Dimensions: 1080 x 1920 pixels
Aspect Ratio: 9:16

Note: For the best results, keep key visual elements within the center safe zone to avoid overlapping with captions or UI elements.

4. Instagram Carousel Post Dimensions

Carousel posts use the same aspect ratios and sizes as square, portrait, and landscape feed posts:

Square: 1080 x 1080 pixels
Portrait: 1080 x 1350 pixels
Landscape: 1080 x 566 pixels

Tip: Consistency is key. Ensure each slide in your carousel is the same size for a cohesive look.

5. Instagram IGTV & Video Post Dimensions

Instagram’s video format specs have evolved. Here’s what to know for video posts:

Feed Video (Short-form): 1080 x 1350 pixels recommended
Aspect Ratios Supported: 4:5, 1:1, and 1.91:1
IGTV Vertical: 1080 x 1920 pixels (9:16)
IGTV Horizontal: 1920 x 1080 pixels (16:9)

Your choice depends on how and where users consume your video content. Mobile-first? Stick to vertical formats.

Instagram Profile and Highlight Covers Dimensions

1. Instagram Profile Picture Dimensions

Size: 320 x 320 pixels
Displayed as a circle, so keep important details centered

2. Instagram Highlight Cover Dimensions

Size: 1080 x 1920 pixels
Displayed in a 1:1 circle format, so design accordingly

Having crisp, branded highlight covers enhances brand credibility and keeps your profile cohesive.
