There is no one definitive answer to this question. It depends on your blog’s content, audience, and overall design. However, here are a few factors to consider when choosing blog photo size:
The average blog reader will only look at a photo once or twice. So, it’s important to keep photo sizes small and easy to scroll through.
Some bloggers choose to keep their photos small in order to conserve bandwidth and avoid slowing down their blog.
Large photos can be distracting and take up too much space on a blog page. When choosing photo sizes, think about how much space you want to devote to your images and how many people will be viewing them at once.
Ultimately, it’s up to the blogger to decide what size photos work best for their blog. However, using these guidelines as a starting point will help you make informed choices about which photos to include on your blog and how best to display them.
