Klaviyo Email Image Sizes 2026: The Complete Guide
Learn the correct Klaviyo email image sizes for 2026. Header banners, product grids, logos, and more — every dimension for sharp, fast-loading emails.
Getting Klaviyo image sizes wrong is the fastest way to break a campaign before it lands. Oversized header images slow load times and trigger spam filters. Images wider than 600px overflow on mobile and get clipped in Apple Mail. Product grids look misaligned when photos aren't cropped to a consistent ratio. This guide gives you the exact Klaviyo email image dimensions for 2026 — headers, product blocks, logos, and everything in between.
Klaviyo Email Image Sizes at a Glance
| Image Type | Recommended Size | Notes |
|---|---|---|
| Email header / hero | 600×200 px (3:1) | Use 600×300 px for a taller hero |
| Inline body image | 600×400 px max | Narrower for multi-column layouts |
| Product image (1-column) | 600×600 px | Square ratio for consistent display |
| Product image (2-column) | 280×280 px | Accounts for template side padding |
| Product image (3-column) | 180×180 px | Minimum; use sparingly on mobile |
| Logo (header) | 200×60 px | PNG transparent, under 40 KB |
| Social icons (footer) | 32×32 px | PNG transparent |
| Retina upload size | 1200px wide | Display at 600px for double density |
| Max file size (per image) | Under 200 KB | Total email budget under 3 MB |
Header and Hero Images
The header image sits at the top of your Klaviyo email and is the first thing subscribers see. Klaviyo's default template container is 600px wide, so your header should be exactly 600px wide — never wider.
For height, 200px is the minimum that gives a banner enough visual weight. Many brands use 300px for a taller, more immersive hero. For product launches or seasonal sales campaigns, heights up to 400px work well — just keep the design focused, since taller headers push body content further down.
Retina screens: iPhones, MacBooks, and most Android flagships display at 2× pixel density. A standard 600×200 px header looks fine on most screens but slightly soft on high-resolution displays. To get crisp results on Retina, upload at 1200×400 px and constrain the display width to 600px in your template HTML. This doubles the effective resolution without changing how the image looks in the email.
Template padding: Klaviyo's default email templates add 20px padding on each side of content blocks. Your header will render at the full 600px width only if you set the image block padding to 0. If you're using a template with built-in side padding, your effective image width is 560px — design accordingly, or remove the padding for full-bleed headers.
Product Images and Grid Layouts
Product images are where Klaviyo emails win or lose the click. The most common layouts in Klaviyo are:
The golden rule for product grids: all images must share the same aspect ratio. Mixing portrait and landscape product photos inside a grid causes rows to misalign and breaks the visual rhythm of your email. Pick one shape — square (1:1) is the safest — and crop all product images to match before uploading.
Retina sharpness: Product images at 280×280 px will look soft on Retina screens in a 2-column layout. Upload at 560×560 px and let the template display them at 280px. The doubled pixel density will keep product details crisp on high-resolution displays.
Logo and Footer Images
Your header logo should be a PNG file with a transparent background. A width of 200px at a height of 40–80px (depending on your logo shape) works for most email templates. Do not upload a logo wider than 300px — it dominates the header and crowds other elements.
Dark mode: A growing share of email clients render in dark mode. If your logo is dark on a transparent background, it will disappear against a dark email background. Prepare a version with a white or light-colored logo on a transparent PNG so it inverts cleanly.
Footer social icons: Most Klaviyo footer templates include rows of social media icons. Standard size is 32×32 px or 48×48 px. Use PNG files with transparent backgrounds for clean rendering across email clients.
File size: Logo and icon files should stay under 40 KB. Footer areas load last — keep them as light as possible.
Mobile Rendering and Image Display
Over 60% of Klaviyo emails are opened on mobile. Klaviyo's responsive templates stack multi-column layouts into single columns automatically on small screens — but image sizing still matters:

Frequently Asked Questions
What is the standard image width for Klaviyo emails?
Klaviyo's default email template container is 600px wide. All images should fit within this width. Images wider than 600px will be scaled down by most email clients, which can cause layout issues or horizontal scrolling on mobile.
Can I use WebP images in Klaviyo emails?
No. WebP is not supported by Gmail on mobile, Outlook (all versions), or Apple Mail. Any WebP image uploaded to Klaviyo will appear as a broken image for a significant portion of your subscribers. Use JPG for photos and PNG for graphics with transparency.
How do I get sharp product images in Klaviyo on Retina screens?
Upload your product images at double the intended display size. For a 280×280 px display slot in a 2-column layout, upload a 560×560 px image. Klaviyo will display it at 280px, and the doubled pixel density will keep it crisp on Retina screens.
Why does my Klaviyo header image look narrower than expected?
Klaviyo's default content blocks have 20px padding on each side, reducing the visible area to 560px. Set the image block's padding to 0 in your template to let a 600px header extend edge-to-edge, or design your header at 560px to fit within the default padding.
What file size should Klaviyo images be?
Keep individual images under 200 KB and ideally under 100 KB for body and product images. Your total email (including all images) should stay under 3 MB to avoid deliverability issues and slow load times on mobile connections.
