Test run byClean CommitCRO agency
Commentary byLiftArchiveOur analysis, not theirsShowing larger product images in a grid on desktop product pages produced an 11.9% rise in conversion rate and 14.5% more orders.
Clean Commit ran this test for an anonymized Shopify store and published it in its A/B test library.
We count it as inconclusive: with 2,552 desktop visitors over 16 days, the variant had a 70.7% probability of winning and only 13% statistical power.
- Conversion rate: +11.9%, with a 70.7% probability of beating the original. Not significant.
- Orders: +14.5%, and revenue per visitor: +8.8%.
- Add-to-cart rate: -6.6%, a negative result.
- Average order value: -2.8%, slightly negative.
The change
A small desktop gallery becomes a grid of larger product images.

Control
A desktop product page with a smaller image gallery.
Variant
Larger product images laid out as a grid on desktop product pages.
Why it likely came out this way
Our reading of the result, not the practitioner's claim.
- Bigger images let shoppers see details without clicking through a slider.
- A grid shows several angles at once, which may answer questions about the product faster.
- With a small sample and 13% power, the gap could easily be chance.
Caveats: Only 2,552 desktop visitors over 16 days, with 13% power, so the test was far too small to confirm a lift. Add-to-cart rate fell 6.6%.

How to run this test on your store
- Hypothesis
- If we show larger product images in a grid on desktop, then conversion rate will rise because shoppers see product details clearly and hesitate less.
- Primary metric
- Conversion rate on desktop
- Guardrails
- Add-to-cart rate
- Average order value
- Who should test it
- Desktop-heavy stores selling visual products like apparel or home goods with several good photos per product. With few images or mostly mobile traffic, the change has little room to work.
Questions
Do bigger product images increase conversion rate?
They can. This test showed an 11.9% conversion lift on desktop, but the sample was too small to be sure.
Is a grid better than an image slider?
A grid shows several images at once without clicks.
This test hints it may help, but it needs more traffic to confirm.
