Image SEO · Answer

How big should a blog featured image be?

A featured image should fit its real template display size and keep its subject clear. Choose a suitable crop, compressed format and responsive dimensions rather than an arbitrary giant file. To apply this to your website, start with the specific page or setting involved. The image displays without stretching, preserves the important subject and does not dominate page weight. Follow the quick checks below or use the linked full guide for a more complete walkthrough.

A quick way to handle this

Start by confirming the live URL or record involved and what the visitor is trying to accomplish. Crop the visual so the subject remains visible on desktop and mobile; export at a sensible width and compressed quality.

Add the width, height, descriptive file name and meaningful alt text when the image conveys information.

Practical example

A 1200×675 guide illustration fits a 16:9 template; a portrait-only photo might need a second crop.

This is a hypothetical illustration; verify the facts and settings for your own website before applying it.

How to check the result

The image displays without stretching, preserves the important subject and does not dominate page weight.

Check the public version of the page, not only an editor preview. Record the affected URLs and whether any remaining issue needs a deeper review.

One mistake worth avoiding

Uploading a 6000-pixel raw photo for a 900-pixel article card.

Search engines choose their own ranking and indexing outcomes. Focus on producing an accurate, usable page rather than promising a particular placement.
