Website Hero Image Size Reference
Recommended hero image dimensions, compression tips, mobile cropping notes, and page speed advice.
| Use case | Recommended approach | Quality note |
|---|---|---|
| Main image | Use a clean, high-quality image sized close to the final display area. | Avoid stretching small images into large spaces. |
| Thumbnail | Crop intentionally so the subject is still clear at small sizes. | Text-heavy thumbnails need extra sharpness. |
| Website upload | Resize first, then compress, then rename the file clearly. | Large original photos should rarely be uploaded untouched. |
| Social sharing | Preview the crop before publishing because platforms may trim edges. | Keep important details away from the edge. |
Best workflow
Start with the best original image you have. Make a copy, resize it for the platform or page area, compress it carefully, and preview the final result before publishing. The right image size is not only about exact pixels. It is about making the image look clean while avoiding unnecessary file weight.
Common mistakes
The most common mistakes are uploading oversized camera files, using tiny images in large areas, cropping faces or product details awkwardly, and forgetting to check the result on a phone. A few minutes of preparation can make a page or profile look more professional.
Extra platform preparation tips
Platform images need more than a correct pixel size. They also need a strong crop, clear subject placement, and enough breathing room around important details. Avoid putting text, faces, logos, or product edges too close to the border because previews and mobile layouts can crop images differently.
Before uploading, create a clean final copy instead of using your original master image. Resize the copy, compress it carefully, and preview it at both full size and small thumbnail size. If the image includes text, check that the text is still readable after compression.
Best workflow for this image type
- Start with a high-quality original image.
- Crop for the final layout, not just the center of the photo.
- Resize to a practical export size.
- Compress the image while checking important details.
- Save with a clear file name so you can find it later.
Platform image quality notes
Platform image sizes are useful starting points, but the final crop matters just as much. Keep faces, logos, product details, and important text away from the edge so previews, mobile layouts, and thumbnails do not cut them off.
Before uploading
Create a dedicated export copy instead of uploading your original master file. Resize for the platform, compress carefully, and preview the image at small size. If the image looks unclear as a thumbnail, simplify the crop or use a stronger source image.
Business use
For business profiles, product listings, and branded posts, consistency matters. Use similar crops, clean backgrounds, readable text, and file names that make your image library easier to manage later.
Reference page notes
Image size references should be treated as practical starting points, not rigid rules for every situation. Platforms and layouts can crop images differently across mobile, desktop, previews, thumbnails, and embedded cards. Always check how the image looks in context before publishing.
Better export habits
Create a final copy for each platform or page instead of reusing one master image everywhere. A website hero, profile image, marketplace photo, blog image, and social post each deserve their own export size and crop. This keeps images sharper and avoids awkward cuts.
Professional polish
For business and brand images, consistency matters. Use clean crops, balanced spacing, readable text, and similar visual treatment across related images so the final page or profile feels intentional.
