Size Guide Popup: Answer "Will It Fit?" Right on the Product Page

"Will this fit?" is the question standing between a lot of shoppers and the buy button - and when they guess wrong, it comes back as a return. A clear size guide, right on the product page, answers it in the moment and quietly does two jobs at once: more confident buyers, fewer returns.

A size guide popup puts your size chart one tap away, right where shoppers decide. A "Size guide" link sits next to Add to cart; tapping it opens a clean popup with your measurements for each size - so the shopper checks their fit and buys the right one the first time, without leaving the page.

Here's the whole thing - built for a store just by describing it:

What your customer sees

A shopper lands on a product and sees a "Size guide" link right by Add to cart. One tap opens a popup with your size chart - a row for each size and its measurements - so they can match their fit without hunting through the description or leaving the page. They pick the right size and add to cart with confidence. See it live on the breezy summer shirt in our demo store.

• Right where they decide - the link sits next to Add to cart, not buried at the bottom of the page.
• Inches or centimetres - shoppers switch between the two, so it reads naturally wherever they are.
• Your chart, your words - a custom popup title and button label, and as many size charts as you need.

Where it earns its keep

Anything sold in sizes - apparel, footwear, rings, kids' wear - where a wrong guess means a return and a refund. A size guide catches the doubt at the exact moment it comes up, so more shoppers buy, and more of them buy the size they'll keep.

It pairs naturally with a back-in-stock signup - when the right size is sold out, shoppers can ask to be told the moment it returns instead of leaving.

How to add a size guide to your Shopify store without a developer

You don't wire anything up or write any code. You describe what you want - "add a size guide popup to my product pages" - and Trooix builds it for your store. Create as many charts as you need with a row per size, set the measurements, and assign each chart to the right products. Want it to look or read a certain way - a different title, button label, or layout? Describe the change and Trooix tailors it. That plain-English build is the heart of what Trooix does.

Questions, answered

What is a size guide popup?

It's a "Size guide" link on your product page that opens a popup with your size chart - the measurements for each size - so shoppers can check their fit in the moment and buy the right size without leaving the page.

Can shoppers switch between inches and centimetres?

Yes. The popup lets shoppers toggle between inches and centimetres, so the chart reads naturally wherever they shop.

Can different products use different size charts?

Yes. Create as many charts as you need - each with its own sizes and measurements - and assign each one to the right products, so a shoe chart shows on shoes and an apparel chart on apparel.
