CMS Max product media guide

Product Image Sizes and Aspect Ratios

Build a consistent catalog with clear source images, stable frames, and responsive delivery.

CMS Max supports five product-card aspect ratios and two image-fit modes. Choose the system before preparing the catalog so photography, uploads, cards, product pages, feeds, and ads stay aligned.

  • Five aspect ratios
  • Cover or contain
  • Responsive source sets
  • Known dimensions

Supported storefront ratios

Choose one frame before the catalog grows.

The dimensions below are practical export starting points at a 1200-pixel primary dimension. The ratio is the governing rule; source requirements can vary by photography, zoom, feed, marketplace, ad, and template.

Image fit

Decide whether the frame or the full product wins.

The active image mode changes what customers see when a source image does not match the selected frame.

Cover

Fill the frame

Creates consistent edge-to-edge cards, but can crop the top, bottom, or sides. Keep the product and critical labels inside a safe center area.

Contain

Show the whole image

Preserves the complete source image, but may add space around products with different proportions. Use a consistent source background.

Responsive delivery

Upload a strong source and let the browser choose an appropriate delivery size.

CMS Max managed-image processing can create CDN URLs and responsive source sets, preserve known dimensions, and output WebP at the configured quality. The browser can then select a candidate based on layout and device conditions.

Source
Sharp, well-lit, correctly cropped, color-consistent, and free of unintended text or watermarks.
Markup
Useful alternative text, intrinsic width and height, responsive srcset, and an appropriate sizes value.
Template
Stable aspect ratio, object fit, loading behavior, zoom expectations, and no layout shift.
Channels
Verify storefront, product feed, search, social, ad, marketplace, email, and print requirements separately.

Catalog media workflow

Make product imagery an operating standard.

Document photography ownership, naming, background, angle, crop, ratio, quality review, accessibility, rights, replacement, feed, and archive rules before a large import.

  1. 01

    Select the ratio

    Choose the catalog frame and object-fit behavior from real representative products.

  2. 02

    Prepare sources

    Use a consistent background, crop, color treatment, safe area, file name, and product identity.

  3. 03

    Verify channels

    Test list cards, product detail, variation selection, zoom, search, feeds, ads, social, and mobile.

  4. 04

    Govern changes

    Record ownership, rights, replacements, broken sources, duplicate files, and stale channel caches.

Product image FAQ

Use the ratio as a system, not a one-time crop.

Test real products with different shapes before applying one media rule across the entire catalog.

Which aspect ratios does CMS Max support for product listings?

The current eCommerce image settings expose Landscape 4:3, Landscape 3:2, Square 1:1, Portrait 3:4, and Portrait 2:3. Square 1:1 is the default when no supported value is selected.

What product image size should I upload?

A 1200-pixel primary dimension is a practical editorial starting point for the five documented ratios, but it is not a universal upload requirement. Start from a clean, sharp source large enough for the intended storefront and feed channels.

Should every product use the same ratio?

Use one primary ratio consistently within a catalog or category unless the design explicitly supports a mixed system. Consistency keeps product cards, comparison, and scanning stable.

What is the difference between cover and contain?

Cover fills the frame and may crop edges. Contain keeps the whole image visible and may leave unused space. CMS Max currently supports both object-fit modes.

Does CMS Max create responsive image variants?

CMS Max can rewrite managed image HTML to a CDN URL with WebP output, quality settings, `srcset`, `sizes`, and known width and height values. Product media also exposes responsive source sets where the active template uses them.
