A 350 ml and 500 ml mug can look identical when both fill their image frames.
Product images that explain size and scale
Supplement images with dimensions and a known reference when size affects choice. An attractive crop does not establish scale.
Research context: Baymard · Images that establish scale ↗
Use documented dimensions and correct units. Body measurements and garment measurements are different information.

Task and expected result
- 01
Compare both mugs and find capacity without interpreting the illustration.
- 02
On a real item, verify dimensions describe the product rather than packaging.
- 03
Ask a participant to explain the expected size before ordering.
How to investigate value
Ask shoppers to explain their variant choice and fit. Later measure confirmed purchases per eligible product visitor, with return reasons as follow-up.
Watch for side effects
Wrong sizes, unknown details shown as facts, mismatched expectations and product-related support/returns.
This is a proposed investigation, not a measured result. Choose one hypothesis and define the audience before testing.
