Aspect Ratio

Before we start to introduce photo sizes we need to understand what is aspect ratio. It is a keyword used to express the size of a photo.

Aspect ratio is the relationship between the width and length of an object, and in this article, we will mainly use it to express the size of a photo. It is usually in the form of AxB, e.g. 1x1, 2x3. You can quickly know the shape of a picture by its aspect ratio. For example, 1x1 means a square image, and 2x3 means a rectangle image.

Blog Post Image Size:

Without a doubt, captivating photos draw viewers' attention in the digital era of social media. You may add photos to your blog to make them more attractive. It is recommended to use photos of the same width to add to your posts so they will look neater and more harmonious.

Blog image size choosing is related to the content area of the blog post.

Instagram: The Instagram image is square and uses a standard 1x1 image to create a standard Instagram image, the most common size being the 1080x1080 px we mentioned earlier. If your photos have more pixels than this value, it's recommended to resize your photos for Instagram, otherwise the image quality may be compressed.
