Vinted contextualises parcel size by giving a visual description of what small, medium, and large means, and auto-recommends a size based on the item itself.
Behind this Bite
This works because it's easier to visualise "a shoebox", rather than "15 inches by 7 inches".
By being easier to visualise, it reduces the effort of making this decision.

Insights
Framing is how information is presented, shaping perception and decisions. Vinted uses real-world objects like "shoebox" to frame parcel sizes, making choices feel more concrete and less abstract.
Specificity shows that clear, relatable descriptions (like "fits in a shoebox") are easier to act on than vague measurements. This helps users feel more confident and reduces anxiety when picking a parcel size.
Cognitive Load is the mental effort needed to complete a task. Vinted lowers cognitive load by using visual cues and auto-recommendations, which means users spend less time and effort deciding.
Smyths uses a similar pattern, showing a "Fits in Most Cars" badge for large toys. Both Vinted and Smyths use clear, visual labels so users can quickly judge size without extra research or guesswork.
Vinted also helps users price items by showing similar listings. Both features use relatable context and recommendations, making complex decisions—like price or parcel size—much simpler and faster.
