How do I keep product photos consistent across the whole catalogue?
By Dan BartleyUpdated 4 minute read
The short answer
Write an image spec before anyone shoots or edits: the aspect ratio, how much of the frame the product fills, the background, the shadow, the light direction, the colour space and the file naming. Then lock it into a fixed setup, a crop template and an editing preset, and check every new image against a reference frame before it goes live.
What should a product image spec include?
Every decision that changes how one image sits beside another: the ratio, the fill, the background, the shadow, the angles, the light, the colour and the files. Write it once and give it to everyone who shoots, edits or uploads.
| Spec item | What to set | Why it matters |
|---|---|---|
| Aspect ratio | One ratio for every main image, such as square | Mixed ratios make the collection grid uneven |
| Fill and padding | The same margin around every product, set as a percentage of the frame | Products jump in size from tile to tile without it |
| Background | One exact colour value, not just white | Off-white and pure white side by side look like a mistake |
| Shadow | Natural, soft drop or none, used the same way everywhere | A floating product next to a grounded one looks pasted in |
| Angles and camera height | A shot list per product type, with the camera height for each | Every chair in the range is seen from the same eye level |
| Light | Direction, softness and colour temperature | Highlights and shadows fall the same way across the range |
| Colour | White balance from a grey card, exported in sRGB | The same fabric looks the same colour on every product |
| Files | Pixel size, format, and names built from SKU, colour and view | Uploads, feeds and future edits stay manageable |
| Gallery order | Main image, angles, detail, scale, then lifestyle | Buyers find the same information in the same place on every page |
For pixel size, Shopify says 2048 x 2048 pixels usually displays best for square product images.
Why do my collection pages look messy?
Because the main images use different aspect ratios, or different amounts of space around the product. Fix the ratio first, then the padding.
Shopify’s help pages say that images displayed side by side on collection pages show at different sizes unless the featured images share one consistent aspect ratio. Many themes, Dawn among them, also let you force a square or portrait ratio on product cards, which masks the problem on the grid but crops images you have not checked.
The quick version of this fix is in why a collection page looks messy when images are different sizes.
How do I keep new product photos matching the old ones?
Keep a reference frame for each product type and compare every new image against it, side by side, before upload. Record the setup so it can be rebuilt exactly.
- A reference frame for each product type, saved where the whole team can find it
- A setup sheet: light positions, distances, camera height, lens and settings, with photos of the set
- One editing preset per setup, applied to every image rather than edited by eye
- A crop template or action that sets the ratio and padding automatically
- A final side-by-side check against the reference frame, and against the grid it will join
When a product cannot be matched to the reference frame, reshoot or remake it rather than patching it.
How do I fix a catalogue that is already inconsistent?
Triage it. Re-crop and re-pad the main images to one ratio first, then replace the photos that cannot be fixed, starting with the best sellers and the products in your ads.
- Export the image list from your store and flag every main image that breaks the ratio, background or padding rules
- Batch re-crop and re-pad the images that only need geometry fixed
- Batch-correct backgrounds and colour where the photo itself is sound
- Replace the rest, in order of revenue, with new images made to the spec
How do I keep consistency across variants and sales channels?
Make every colour variant from the same master setup, so only the colour changes, and export each channel’s crop from one master file rather than editing each copy separately.
Variant images need to show the variant. Google’s image requirements ask that a product with several colours or styles shows only the single variant being sold in each listing, and rule out added text, watermarks and borders. Square and vertical crops for Meta placements come from the same master, so the product looks the same in the feed as on the page.
Can new product frames be made to match my existing photography?
Yes, if whoever makes them works to your spec. Give them the spec sheet and a reference frame for each product type, and check the first frames against your current grid before the rest are made.
Bartley Studio makes product frames from a couple of phone photos of each product. The first look arrives in 2 to 3 working days, and one round of changes to the creative direction is included. Files come in two sets, web-compressed and full resolution, pre-cropped and named, and any final image that does not match the real product is re-edited until it does, with no cap and no extra fee.
Other questions people ask about this
What aspect ratio should product images be?
Square is the safest default, because it suits most themes, marketplaces and catalogue ads. Portrait suits apparel. Whichever you choose, every main image should use it.
Should every product fill the frame by the same amount?
For the main image, usually yes, because a consistent margin makes the grid look ordered. Where relative size matters, such as side tables beside sofas, show it in scale shots further into the gallery.
How should product image files be named?
Build the name from the SKU, the variant and the view, so files sort together and match the feed. Consistent names also make alt text and bulk replacements easier.
