Back to the list
82% of online apparel stores fail to provide clear sizing info, leaving shoppers to guess. Unlike in-store shopping, where trying things on is easy, online buyers rely on images, descriptions, and often inconsistent size charts, making the risk of a wrong fit much higher.
It’s time for Sizing UX 2.0. A better sizing experience doesn’t just help customers, it drives conversions and reduces returns. Some brands use size recommenders or improved charts, but the real game-changer? A multi-touchpoint approach that integrates sizing guidance across the entire shopping journey.
We’ve gathered best-in-class practices to help brands get sizing right.
The Size Recommender
Use a size recommender to suggest the perfect fit for your customers. Asking about body type is a great start. Giving them the ability to create their own body shape takes it to the next level.
Auto-select the recommended size
Once the right size is calculated, automatically recommend it on each PDP, making it easier for customers to add the perfect size to their basket with just one click.
Boost size recommender access
Drawing attention to the Size Recommender on your PDP is essential. Higher usage means fewer returns, better conversion rates, and happier customers.
Bespoke, intuitive size charts
Every product has its own fit; don’t rely on a generic size chart. Instead, offer a tailored guide for each item, with international measurement conversions and product measurements mapped to the human body.
Measurement instructions
Show, don’t tell: offer clear measurement instructions on top of sizing info. Use a human model to highlight exactly where to measure, making it easy to get the right fit.
The 'Double Size Check'
If customers are adding two sizes of the same product, check if it’s intentional or if they’re unsure. Let them know you can help them pick the right one anytime!
Same product, different models
Always show how the product fits on real people, including the model’s height and size worn. For the best sizing and fit UX, feature multiple models with varying heights and body types.
Play around with different heights
Let customers explore different heights and body types for the same product to see how the fit varies.
#CommunityLooks
While sizing may not be mentioned, real-life, user-generated content provides valuable insights into how the product looks on different body types.
⚠️ Watch out for this common pitfall: Garments are often clipped during photoshoots, distorting the fit and creating misleading size expectations. Ditch the clips!
Personalized product reviews
Encourage detailed reviews that focus on fit for different body types. Highlight reviews from customers with similar body measurements to provide the most relevant insights on fit, comfort, and sizing.
Smart nudges
Help customers make the right choice by adding clear fit indicators. These quick, intuitive nudges eliminate guesswork and set accurate expectations before purchase.
A size and fit information section
Advise your customers on how materials can affect the fit. Whether it runs true to size and the kind of fit they can expect (regular, oversized, slim).
Link sizing and fit to historic customer purchases
Integrate sizing and fit with customer data in your CRM and accounts. Let customers compare new items with measurements from their historic purchases to increase confidence in size selection and customer loyalty over time.
A dedicated sizing and fit landing page
Create a special landing page with key details on sizing and fit; how size recommendations work, the data behind them, privacy protection, and all available tools to find the best fit.
A check-out nudge
If customers add the same product in different sizes, remind them to use the size recommender to confirm the best fit.
⚠️ Watch out for this common pitfall: Enhancing sizing tools is great, but don’t lose the customer. Use a new tab or direct link back when redirecting to external size charts or info.
