OTTO image size guide 2026
Quick answer
Integration providers quote OTTO Market's minimum image size as 500 x 1000 px, with a maximum width of 4500 px, in JPG or PNG and RGB. The main image should be cropped or on a light neutral background with about 85% fill. We could not confirm this on an OTTO page, so check your partner account.
We could not read OTTO's image rules on a public OTTO page. Everything below comes from integration providers, mainly Lengow and plentyONE, that quote OTTO in their help material. Your OTTO partner account decides what applies.
The 1000 px recommendation and 20 MB file figure in the table are our own working values. Integrators give 500 x 1000 px as the minimum, and we found no published file size limit.

What integrators quote
The quoted minimum is 500 x 1000 px, with a maximum width of 4500 px, in JPG or PNG and RGB. CMYK files are described as technically not permitted. One photo studio instead recommends a 4:5 portrait at 2400 x 3000 px, which we did not use because we could not trace it to OTTO. A larger master does no harm if you want one.
Main image content
The main image should be cropped or on a light neutral background, such as light grey, white, off-white or beige, with the product making up about 85% of the area. Retailer names, logos, text, icons and watermarks are described as prohibited, and so are test seals and certifications such as FSC or Oeko-Tex. Keep those facts in your product attributes.
Questions
How do I confirm OTTO image rules?
Log in to your OTTO partner account or ask partner support. Connector support teams can also tell you what errors your feed has returned. Save the answer with your image export settings, so your whole team builds photos against the same figures.
Can I use lifestyle pictures on OTTO?
The guidance we found applies its background rule to the main image, and describes additional images as a place for other views. Lead with a clean product picture and use lifestyle shots after it. We could not confirm this on an OTTO page.
Why does my OTTO feed report missing main images?
Lengow says the HAUPTBILDER_NICHT_VORHANDEN error can mean the linked images fail technical requirements, not only that they are absent. Open the link in a browser to confirm it returns the image, then test that file here for size and format.
Is there a maximum file size for OTTO images?
We found no published file size limit. The 20 MB figure in our table is our own working value, as is the 1000 px recommendation, so neither should be read as an OTTO rule. Ask partner support if you need a firm figure.
Should I use a 4:5 portrait image for OTTO?
You can, but we could not trace that advice to OTTO. One photo studio recommends a 4:5 portrait at 2400 x 3000 px, so we left it out of our figures. A larger master does no harm if you want one, as long as it stays within the quoted width.
Can retailer logos or text go on an OTTO main image?
Not according to integrators, who describe retailer names, logos, text, icons and watermarks as prohibited, along with test seals and certifications. We could not confirm this on an OTTO page. Keep those facts in your product attributes.
