ESC Size Charts Alternatives for Shopify

The strongest ESC Size Charts alternatives for Shopify are Kiwi Size Chart & Recommender and True2Size if you want a chart app with size advice, Fit Quiz if you want a questionnaire-based recommender, and your theme's built-in size chart if you only need a simple table. ZeDaq.ai is a different route: it turns your chart into a size suggestion from a photo scan.

ZeDaq.ai publishes this blog. Competitor details come only from each company's Shopify App Store or Theme Store page, checked November 2026. If you are also weighing try-on tools for the same product pages, see our guide to try-on apps for Shopify.

What does ESC Size Charts do?

ESC Size Charts is made by Eastside Co. Its Shopify App Store listing (checked November 2026) describes charts built from a template or from scratch, with images, icons and text. Charts can be assigned by tags, collections, products, vendors or product type, and they work with Online Store 2.0 through app blocks.

On that listing, the Basic plan is free for up to 3 charts with an ESC watermark. Premium is $4.99 a month for unlimited charts, no watermark and chart import and export, with a 7-day free trial. The listing showed a 3.3 rating from 137 reviews when we checked.

Why would you look for an ESC alternative?

Store owners usually start looking for one of these reasons:

• You want a size recommendation, not only a table. A chart still leaves the shopper to measure and decide.
• You need more languages or unit switching. Stores selling across borders want charts that adapt to the shopper.
• You want analytics. Some apps report how the size tool is used.
• You want fewer apps. If your theme already shows a size chart, a separate app may be unnecessary.
• Support or reliability. Read recent reviews on any listing before you commit.

For a head-to-head on the most common switch, our Kiwi Sizing vs ESC Size Charts comparison goes feature by feature.

Which alternatives can you use instead?

Kiwi Size Chart & Recommender

The Kiwi listing by Staytuned showed a 4.7 rating from 1,242 reviews when we checked in November 2026. It lists chart import from images, product descriptions or CSV, product or collection rules that auto-apply to new products, unit switching by location and AI-powered size recommendations.

Plans on that listing run from Free, with up to 3 published charts and a watermark, to Premium at $7.99, Plus at $14.99 and Ultimate at $26.99 a month. Paid plans list a 14-day free trial, and Plus and Ultimate note extra charges may apply based on order volume.

True2Size: Chart & Recommender

The True2Size listing showed a 5.0 rating from 4 reviews when we checked in November 2026. It lists size charts with multiple tables, images and text, plus a recommendation with a confidence score after a short questionnaire or measurement entry.

Its Free plan includes unlimited size charts with no watermark and up to 500 add-to-carts a month. Starter is $19 and Pro is $49 a month, each with a 14-day free trial, according to the same listing. It is a newer app with few reviews, so test it on a development store first.

Fit Quiz: Size Recommender

The Fit Quiz listing by Easysize showed a 4.1 rating from 39 reviews when we checked in November 2026. It focuses on recommendations rather than charts, with fit, width and length advice per product and support for UK, EU, US and custom size scales.

Plans on that listing are Starter at $29, Pro at $109 and Premium at $249 a month. Each adds $0.15 per item added to cart with a Fit Quiz recommendation, and all include a 10-day free trial.

Your theme's built-in size chart

You may not need an app at all. Shopify's free themes Dawn and Horizon both list "Size chart" among their features on the Shopify Theme Store, checked November 2026.

A theme chart is usually a page or pop-up you fill with your own table. It is enough for simple ranges, but it won't recommend a size.

ZeDaq.ai: your chart, applied for the shopper

ZeDaq.ai uses your chart differently. You enter your size guide in the Shopify app, one chart per garment type: tops, outerwear, dresses and bottoms.

On the product page, the shopper taps "Find my size," uploads one photo and types their height. A 30-second scan measures them and returns one label from your chart. When a shopper falls between sizes, it sizes up to the largest relevant measurement. The same app adds virtual try-on, so shoppers can also see the garment on their own photo.

How do you switch away from ESC without losing charts?

Switching takes an afternoon if you plan it. Follow these steps in order.

1. Export or copy every chart. ESC Premium lists chart export. On Basic, copy each table into a spreadsheet.
2. List your assignment rules. Note which tag, collection or product type each chart is attached to.
3. Check units and gaps. Make sure each size range meets the next, so no shopper falls between sizes.
4. Install the new app on a development or preview theme. Rebuild charts there first.
5. Test five products on a phone. Check one from each garment type.
6. Switch the live theme, then uninstall ESC. Remove its app block so no empty space is left on product pages.
7. Watch customer messages for two weeks. Fit questions tell you if a chart was missed.

Worked example: moving a small dress store

Picture a store with three ESC charts: dresses, tops and skirts, each assigned by product type. Here is how the move might look.

• Day one, morning. Copy all three tables into one spreadsheet, one tab per chart. Note that the dresses chart uses bust, waist and hip, while the tops chart only uses bust.
• Day one, afternoon. Fix gaps. If size 10 ends at a 32-inch waist and size 12 starts at 33, make them meet so a 32.5-inch shopper gets an answer.
• Day two. Rebuild the charts in the new app on a preview theme. Attach them by product type, just as before.
• Day three. Test one dress, one top and one skirt on a phone. Then publish the theme and remove the ESC block.

The spreadsheet becomes your master copy. Whatever app you use next, you can rebuild from it in minutes.

What should you test before going live?

Check these on a real phone, not only the desktop preview:

• The chart or size button sits near the size selector, not below the fold.
• Tables scroll sideways or stack without cutting off columns.
• Units match what your shoppers expect.
• Fit notes such as "runs small" show on the right products.

If you sell extended sizes, your theme matters as much as the app. Our guide to Shopify themes for plus-size fashion covers layouts that make long size ranges easy to read.

Should you choose a chart app or a recommender?

Pick based on the question your shoppers ask most:

• "What are the measurements?" A chart app answers this. ESC, Kiwi, True2Size or your theme will do.
• "Which size should I buy?" A recommender answers this. Kiwi, True2Size, Fit Quiz and ZeDaq.ai all try to.
• "How will it look on me?" Only try-on answers this.
