Every product photo has a shape before it has a subject. Square, portrait or landscape: the aspect ratio you choose decides how much of the screen your product fills, whether a marketplace crops off the toe of a shoe or the top of a bottle, and whether your catalogue looks tidy or chaotic in a grid. Most sellers never make that choice deliberately. They shoot in whatever ratio the phone defaults to, upload, and let each platform crop as it likes.

This guide explains how each shape behaves, which ratio each major marketplace expects in 2026, and how to plan one shoot that works everywhere.

The Three Shapes in Plain Numbers

An aspect ratio is simply width to height. A 1:1 image is as wide as it is tall. A 3:4 or 4:5 image is taller than it is wide (portrait). A 4:3 or 3:2 image is wider than it is tall (landscape). The camera on most phones shoots 4:3 by default, and most DSLR and mirrorless cameras shoot 3:2, which is why so many product photos arrive at the editing stage in a shape no marketplace actually wants.

Square (1:1): The Marketplace Default

Square is the safest single choice for e-commerce because it is what most marketplace search grids are built around. Shopee, Lazada, Qoo10 and Carousell display listing covers as squares, and Amazon and eBay search results present products in near-square tiles. Upload a landscape or portrait main image to these platforms and one of two things happens: the platform crops it (often cutting off part of the product), or it letterboxes it with white bars, which makes your product look smaller than the competitor next to it.

Where square works best

Where square struggles

Tall or long products. A floor lamp, a full-length dress or a bottle of wine fills only a narrow strip down the middle of a square, leaving large areas of empty white. Long products such as skateboards, rods or keyboards have the opposite problem. You can rotate a long item diagonally to use more of the frame, but tall items in a square frame will always look smaller than they would in portrait.

Portrait (3:4, 4:5, 2:3): The Mobile-First Shape

Most online shopping now happens on phones, and phones are tall. A portrait image occupies more of the screen as a shopper scrolls, which is why fashion platforms and social commerce have drifted towards it. Instagram moved its profile grid to 3:4 tiles in 2025 and now accepts 3:4 uploads (1080 x 1440 px) without cropping. TikTok Shop supports 3:4 product images and, according to several seller tools, may auto-crop non-3:4 images in some placements.

Some marketplaces go further and make portrait compulsory for certain categories:

The catch

Upload a portrait main image to a square-grid marketplace and you lose the advantage. On Shopee or Lazada, for example, the cover image is still displayed square, so a 3:4 image will either be cropped top and bottom or shrunk with white bars at the sides. Portrait is a category and channel choice, not a universal upgrade.

Landscape (4:3, 3:2, 16:9): The Niche Option

Landscape is the least useful shape for main product images. On a phone it occupies the smallest area of screen of the three, and it usually gets cropped on square grids. It does have its place:

If you sell wide products, a sensible compromise is a square main image with the product filling the width, followed by landscape lifestyle images in the gallery.

Consistency Matters More Than the Ratio Itself

On your own Shopify store, the biggest mistake is not picking the "wrong" ratio. It is mixing ratios. When one product card is square, the next is portrait and a third is landscape, collection pages look jagged, prices and titles sit at different heights, and the store feels unfinished. Most Shopify themes let you choose between adapting to the image, forcing square, or forcing portrait for product cards. Choose a fixed ratio and make every main image match it.

The same applies to your gallery images within a listing. Swiping from a square image to a landscape one makes the page jump on mobile, which is a small but real friction point.

Shoot Once, Crop for Every Channel

You do not need a separate photoshoot for every ratio. Plan for cropping instead:

  1. Shoot loose. Leave generous space around the product on all sides so you can crop square, portrait or landscape without cutting anything off.
  2. Shoot at full resolution. A 12 MP phone photo (4000 x 3000 px) can still give you a 3000 x 3000 square or a 2250 x 3000 portrait crop without upscaling.
  3. Keep the product centred. A centred subject survives every crop. One shoved to the side does not.
  4. Decide your master ratio per category. For example: square for accessories and electronics, 3:4 for clothing.
  5. Export each channel version separately. Do not upload one file and rely on each marketplace to crop it for you.

That last step is where most of the time goes. Tools such as PixelPrep let you batch resize and pad a folder of product photos to each marketplace's ratio and size in one pass, so the same shoot produces a 1:1 set for Shopee and Lazada and a 3:4 set for TikTok Shop without editing each file by hand.

Padding vs Cropping

When converting a portrait or landscape photo to square, you have two options. Cropping removes part of the image and keeps the product large, which is ideal when there is spare background around it. Padding adds white space to the short sides, which keeps the whole product visible but makes it appear smaller. As a rule, crop when you can and pad only when cropping would cut into the product. If you pad, make sure the background colour matches exactly, ideally pure white (RGB 255, 255, 255), so the join is invisible.

Checklist: Choosing the Right Ratio

The right aspect ratio is the one your shopper's screen and your marketplace's grid are built for. Get that right once, build it into your workflow, and every product you add afterwards will look like it belongs.
