In the ever-evolving world of social media, Instagram continues to be a powerhouse platform for sharing images and videos. To make a lasting impression and engage your audience effectively, understanding the importance of the right aspect ratio for Instagram videos is paramount. In this article, we will delve into the significance of aspect ratios, explore the various aspect ratios and sizes for different types of Instagram videos, discuss how to change aspect ratios, and explore different video resizer options to help you create captivating Instagram content.


Why Aspect Ratio Matters on Instagram

Aspect ratio refers to the proportional relationship between an image or video's width and height. It plays a crucial role in how your content appears on users' screens. On Instagram, maintaining the correct aspect ratio ensures that your videos display as intended, optimizing the viewing experience and maintaining the visual integrity of your content. Ignoring aspect ratios can result in poorly cropped or distorted videos that may deter users from engaging with your content.


Different Instagram Video Aspect Ratios and Sizes

Instagram offers various formats for sharing videos, each with its own recommended aspect ratio and size. Here's a breakdown of the key formats:



Aspect Ratio: 9:16

Video Size: 1080x1920 pixels

Instagram Story:

Aspect Ratio: 9:16

Video Size: 1080x1920 pixels

Instagram Stories are ephemeral, full-screen videos meant for a brief but impactful message. The 9:16 aspect ratio ensures a seamless viewing experience in portrait mode.


IGTV (Instagram TV):

Aspect Ratio: 9:16 (Vertical) or 16:9 (Horizontal)

Video Size: 1080x1920 pixels (Vertical) or 1920x1080 pixels (Horizontal)

IGTV allows for both vertical and horizontal videos. Choose the aspect ratio that best suits your content, but keep in mind that vertical videos are often favored for mobile viewing.


Instagram Posts:

Aspect Ratio: 1.91:1 to 4:5 (Square, Landscape, or Portrait)

Video Size: 1080x1080 pixels (Square), 1080x608 pixels (Landscape), or 1080x1350 pixels (Portrait)
