Everything you need to know about Shopify blog image sizes: featured images, in-content photos, thumbnails, and social sharing specs. Get the dimensions right to improve engagement and SEO.

600 x 400 pixels (3:2)
The recommended size for Shopify blog featured images is 1200 x 800 pixels (3:2 aspect ratio). This size is perfect because:
Pro Tip: Some Shopify themes work better with 1920 x 1080 pixels (16:9 aspect ratio). Check your theme documentation or test both sizes to see which displays best.
| Image Type | Recommended Size | Aspect Ratio | Use Case |
|---|---|---|---|
| Featured Image | 1200 x 800 | 3:2 | Main blog post header |
| Featured (Alt) | 1920 x 1080 | 16:9 | Wide-screen themes |
| In-Content | 1024 x 683 | 3:2 | Embedded article images |
| Social Sharing | 1200 x 630 | 1.91:1 | Facebook, Twitter, LinkedIn |
| Thumbnail | 600 x 400 | 3:2 | Blog listing grid |
| Mobile Rendered | 90 x 90 | 1:1 | Auto-generated by Shopify |
When you share a Shopify blog post on social media, the featured image automatically becomes the social sharing thumbnail. However, different platforms have different optimal dimensions:
Universal Solution: Use 1200 x 800 pixels (3:2) for your featured image. This works well across all platforms and Shopify will automatically crop it appropriately for social sharing.
Featured images should be 1200 x 800 pixels. In-content images can be 1024 x 683 pixels for faster loading.
Aim for under 200 KB per image. Use tools like TinyPNG, ImageOptim, or our free resizer.
Name files like "shopify-blog-image-optimization-tips.jpg" before uploading (helps SEO).
Write descriptive ALT text in Shopify: "Person optimizing blog images in Shopify dashboard for faster loading".
Use JPG for photos, PNG for graphics with text, WebP for best compression and quality.
Always preview blog posts on mobile devices to ensure images display correctly at smaller sizes.
Blog images aren't just for aesthetics; they're powerful SEO tools when optimized correctly:
Bad: IMG_1234.jpg
Good: shopify-blog-image-size-guide-2025.jpg
Include target keywords naturally in file names before uploading.
Bad: "Image"
Good: "Comparison chart showing optimal Shopify blog image dimensions for featured images and thumbnails"
ALT text helps search engines understand your images and improves accessibility.
Keep images under 200 KB for blog posts. Page speed is a ranking factor, and heavy images slow down your entire site. Compress images before uploading.
Place images near relevant text. Add captions with target keywords when appropriate. This helps search engines understand the relationship between your content and images.
Shopify automatically includes blog images in your sitemap. Ensure your blog posts are published and indexed for images to appear in Google Image Search.
Over 70% of blog traffic comes from mobile devices. Shopify automatically renders images for mobile, but you can optimize further:
Use for: Featured images, in-content photos
Use for: Infographics, screenshots, diagrams
Use for: All blog images (best choice)
Result: Slow blog loading, high bounce rates, poor mobile experience, and lower SEO rankings.
Result: Featured images get cropped awkwardly in blog listings and social media shares.
Result: Lost SEO opportunities, poor accessibility, and images won't rank in Google Image Search.
Result: IMG_1234.jpg files provide zero SEO value. Use descriptive, keyword-rich file names.
Result: Blog posts shared on social media look unprofessional with poorly cropped thumbnails.
To ensure your blog posts display perfectly when shared on social media:
Shopify automatically uses your blog post's featured image as the social sharing thumbnail. Make it 1200 x 800 pixels.
Go to Online Store → Preferences → Social Sharing Image. Upload a 1200 x 630 pixel default image for pages without featured images.
Use Facebook's Sharing Debugger and Twitter Card Validator to preview how your blog posts will appear when shared.
Different platforms crop images differently. Keep text and key elements in the center of your featured images.
Stop resizing and compressing manually. AI creates perfectly sized blog images automatically at 1200x800 pixels, optimized and ready to upload.
AI generates 1200x800 blog images automatically
Under 200 KB, WebP format, perfect compression
Custom blog graphics, featured images, infographics
The recommended size is 1200 x 800 pixels (3:2 aspect ratio) for featured images. This displays perfectly on all devices and loads quickly when compressed to under 200 KB. For in-content images, you can use 1024 x 683 pixels.
Use a 3:2 aspect ratio (1200 x 800 pixels) for most Shopify themes. Some themes work better with 16:9 (1920 x 1080 pixels). Check your theme documentation or test both to see which displays best on your blog.

Use JPG for photos and featured images (smallest file size). Use PNG for graphics, screenshots, or images with text. For the best quality and smallest size, use WebP format, which is Google's preferred format and 30% smaller than JPG.
Include 1 featured image (required) and 3-6 in-content images for a typical 1000-1500 word blog post. Break up text every 200-300 words with relevant images to improve readability and engagement. More images = better user experience and SEO.
The displayed size depends on your theme, but you should always upload images at 1200 x 800 pixels. Shopify will automatically resize them for different views (desktop, mobile, thumbnails). Using the correct source size ensures the best quality at all display sizes.
