Complete Guide For Instagram Post Sizes (2025)

Instagram has become a powerful platform for businesses and creators alike, offering a variety of ways to engage with your audience. However the bigger it gets the harder it is to keep up. Understanding the different types of Instagram posts is essential.

In this guide, we'll explore the most effective formats for Instagram posts, helping you choose the right approach to enhance your content strategy and connect with your followers in meaningful ways.

The most significant change on Instagram recently is the introduction of new portrait post formats. We’ve transitioned from the traditional square (1:1) posts to a 4:5 aspect ratio, marking a major shift in how content is displayed. Instagram has long been known for its strict adherence to the 1:1 format, but now, while square posts are still allowed, the preview has shifted to a 4:5 layout.

To stay current and optimize your content’s appearance, we strongly recommend adjusting your posting format from 1:1 to 4:5 for all of your feed posts. This simple change can make a big difference in how your posts are viewed and engaged with!

Below, we’ve provided a table of formats and sizes for all the posts you can make on Instagram:

Choosing the right format for your Instagram posts is key to making your content stand out and engaging your audience effectively.

As Instagram evolves, staying updated with changes–like the shift to 4:5 portrait posts– ensures your visuals look their best and are optimized for the platform. Remember to use the right format for the right type of post and respect the recommended sizes as much as possible. This attention to detail will help you get a better response from your followers.

So, adapt your content strategy to these formats and sizes, and watch your Instagram presence thrive!
