Will this fit me?
Size charts are often too general.
Free guide for clothing and shoe stores
Help customers choose the right size online.
Customers do not want to measure themselves, upload body photos or answer personal questions before they buy. They just want to know which size fits best in this exact product.
Zizr helps online stores show clear size guidance directly on the product page, based on the item, model and how customers actually experience fit.
No weight. No body photos. No measuring tape.
Why customers hesitate before buying
When customers are unsure about size, the buying journey slows down. They open the size chart, look for reviews, compare models, add several sizes to cart or leave the page.
Does this brand run large or small?
The brand alone says too little about each model.
Do I need to measure myself first?
Extra steps create friction.
What if I choose wrong?
Uncertainty weakens purchase confidence.
This is what we mean by item-level size guidance.
Size is not just about the brand. It is about the item.
Most merchants already know this: two products from the same brand can fit completely differently.
A pair of trousers can be small in the waist. A dress can feel tight across the hip. A blazer can be narrow across the shoulders. A shoe can feel different because the shape, width or material is different.
That is why it is not always enough to ask which size the customer usually wears in a brand. Good size guidance must understand the product the customer is looking at right now.
Same customer. Same brand. Different recommendation.
A customer does not have one fixed size. The right size can vary with model, cut, fabric, category and how the customer likes the product to fit.
Why: Closer cut through waist and hip
Why: Looser fit and more stretch
Why: Narrow shoulder and less flexible fabric
The example is illustrative. Actual recommendations depend on product data and the customer's fit signals.
Old size guidance asks the customer to do more. Zizr removes friction.
Old way
- Ask the customer for height, weight or body shape
- Send the customer to a general size chart
- Use averages and brand-level logic
- Add more steps before purchase
- Leave the difficult decision to the customer alone
Zizr way
- Show size guidance directly on the product page
- Work without weight and body photos
- Understand differences between products and models
- Learn from real fit signals
- Give customers more confidence before purchase

What to look for in a sizing tool
Use a simple checklist when evaluating solutions for your online store.
Less measurement theatre. More useful size guidance.
Many solutions try to make size choice more precise by asking the customer for more data. More questions do not necessarily mean better guidance.
Good size guidance should not make the customer feel measured or judged. It should help the customer choose the right size with as little friction as possible.
Zizr uses product data, fit signals and learning from actual purchases to provide item-level guidance.
