Ask "does Shopify have a size chart feature?" and the accurate answer is: not as a named feature — but Shopify publishes instructions for building one without an app.

Articles claiming native Shopify "can't do it at all" are slightly off. The help center hosts a tutorial titled "Adding a pop-up size chart to your product pages", laying out four concrete steps that combine a page-reference metafield with a theme pop-up block. The metafields documentation itself uses this as its example: if you sell clothing and want to display a size chart, create a product metafield called Size chart.

The problem is a constraint stated plainly in that same tutorial: you can link only one page in the product metafield. That single sentence largely determines whether you need an app.

This article covers what the native approach genuinely achieves, where it stops scaling, and how six real size chart apps compare on identical axes. Researched September 1, 2026; all pricing is the USD figure shown on the Shopify App Store.

The short answer

If one size chart serves every product, you don't need an app. The official tutorial covers it.

The moment you need different charts per product or collection, native stops being practical. Linking each product to its own page and template is work that scales linearly with catalog size.

If you're adding an app, here's the split:

• Japanese admin UI, running free in production: MP Size Chart & Size Guide (3 charts free, AI size recommender included — though the listing says nothing about watermarks either way, so confirm before shipping)
• Japanese admin UI, with a watermark-free free tier you can rely on: CSC: Size Chart & Size Guide (2 charts free, "No Powered by Watermark" stated outright, setup done for you)
• Cheapest paid tier with unlimited charts: ESC Size Charts ($4.99/month, unlimited)
• Expecting more than 2,000 orders per month: avoid Kiwi Size Chart & Recommender and CSC's Plus tier; consider MP Pro at a flat $12.95/month

What the official tutorial actually does

Four stages.

Create a product metafield definition of type Page (page reference). Storefront access is enabled by default when you create a metafield definition, per the help center, so that setting needs no attention.

Create a new product template and add a Pop-up block inside the Product information section. Set Link label to "Size chart" and connect the Page field to your metafield via a dynamic source.

Build the size chart content as a page under Online Store > Pages.

Select that page on each product and apply the template.

A useful side effect: splitting by product type works. The help center's own example is creating two separate size chart pages for two age groups — a toddler chart and an infant chart — served through different product templates.

There is no table metafield type

This is where the common misconception sits. "You can build a table with metafields" is half wrong.

Shopify's metafield data type list contains no table type. The closest candidate, rich_text_field, is documented as supporting "headings, lists, links, bold, and italics" — and its JSON node types are limited to root, paragraph, heading, list, list-item, text, and link. Rich text metafields cannot contain tables.

Which is exactly why the official tutorial structures things the way it does: build the table as an Online Store page, then reference that page. The table lives in page content, not in the metafield.

Whether the Shopify admin's page editor supports building tables couldn't be confirmed in the documentation. Worth verifying on your own store.

Four places the native approach breaks down

1. One page per product, full stop

The tutorial's exact wording: "You can create as many size chart pages to reference in the metafield as you need. However, you can link only one page in the product metafield."

For a store mixing tops, bottoms, and footwear, that means selecting a page individually on every product. Past a few dozen SKUs, this becomes a real operational cost.

2. Configuration gaps surface to customers, not to you

The help center warns about this directly. If a product uses the template but its page reference is left blank, the link text still renders — and opening it shows an empty pop-up. Shopify's phrasing: "might create confusion for your customers." It's the kind of oversight that shows up on the storefront rather than in the admin.

3. No documented method for variant-level switching

For "the chart changes when the customer selects a size," the official tutorial only covers product-level page references. No variant-linked procedure could be found. Nothing in this research surfaced a native way to do it.

4. It assumes a modern theme

The tutorial requires a theme that supports dynamic sources — meaning Online Store 2.0. For vintage themes, the help center's guidance is to edit theme code or hire a Shopify Partner.

About return-rate statistics, stated precisely

Size chart articles routinely cite "X% of returns are size-related." This needs care.

No Shopify-published return statistics could be found. Everything Shopify's own blog cites comes from outside sources: Rithum's 2025 global survey of 6,000 people ("61% returned apparel because of sizing"), and Coresight Research ("size and fit account for 53% of returns," "24.4% online apparel return rate"). A further figure — "28% average return rate, 80% of it fit-driven" — comes from a statement by a co-founder of Bold Metrics, not from a verified study.

If you reuse these numbers in your own materials, attribute them as "a study by [company] cited on Shopify's blog," not as Shopify data.

Six size chart apps compared

Filtering the Shopify App Store's "Product comparison" category by the "Size charts" feature returns 217 apps as of September 1, 2026. That set mixes in AI virtual try-on tools and spec comparison tables, so the count of genuine size chart apps is considerably lower.

App	Developer	Rating (reviews)	BFS	Free-plan charts	Cheapest paid	Japanese UI	AI recommender
MP Size Chart & Size Guide	Shopplaza (Vietnam)	5.0 (821)	Yes	3, no watermark statement	$6.95/mo ($69.50/yr)	Yes	Included on free plan
Kiwi Size Chart & Recommender	Staytuned (US)	4.8 (1,118)	No	3, watermarked	$7.99/mo	No	Plus ($14.99+)
ESC Size Charts	Eastside Co (UK)	4.1 (123)	Yes	3, watermarked	$4.99/mo (unlimited)	No	No
CSC: Size Chart & Size Guide	TaskHusky (US)	5.0 (93)	Yes	2, no watermark	$6.99/mo	Yes	Advanced ($14.99)
K: Size Charts & Size Guide	Kaktus (Moldova)	5.0 (11)	No	Listing contradicts itself	$1/mo (capped at $9.99)	No	Yes
Quick Size Chart & Size Guide	droplogicx (UK)	2.0 (1)	No	Entirely free	—	No	No

Three readings from that table.

First, the meaningful difference between free plans isn't chart count — it's watermarks. MP, Kiwi, and ESC all allow three charts; CSC allows two. Kiwi states "Kiwi Watermark Included" and ESC states "ESC watermark on charts on Basic Plan," so both mark the chart on their free tiers. CSC states "No Powered by Watermark" outright. MP's listing says nothing about watermarks either way, so confirm with the developer before shipping on it. Only CSC explicitly guarantees a watermark-free free plan.

Second, the Built for Shopify badge and star rating don't track together. ESC Size Charts holds the badge at 4.1. Kiwi, the largest by review volume at 4.8 across 1,118 reviews, doesn't have it. The badge attests to meeting quality requirements — it isn't a satisfaction ranking.

Third, reading only the monthly price will mislead you. Kiwi's Plus and Ultimate tiers, and CSC's Plus tier, add order-volume-based charges. CSC publishes its bands outright — $29.99 to 250 orders, rising through $59.99, $99.99, $149.99, $199.99, and $299.99 above 5,000. Kiwi's Plus and Ultimate tiers say only "Additional charges apply based on order volume," so the App Store listing gives you no ceiling to plan against; check the developer's own pricing page before installing. Evaluate it as a "$14.99 app" and growth will produce an invoice you didn't plan for.

What to look at app by app

MP Size Chart & Size Guide

Formerly Avada Size Chart — the developer's documentation says "formerly Avada Size Chart" outright, and the App Store URL handle is still avada-size-chart. Shopify's own blog calls it "Mageplaza's Size Chart & Size Guide." Three names in circulation; easy to lose in a search.

Launched April 9, 2020; 821 reviews; Built for Shopify. The free plan gives three published charts, 30+ templates, automatic unit conversion, a dedicated size guide page, and an AI size recommender (the listing makes no statement about watermarks). Paid tiers: Growth $6.95/month (10 charts, up to 800 AI recommendations), Pro $12.95/month (unlimited charts, up to 2,000), Advanced $24.95/month (up to 5,000). Annual billing saves 17%; 14-day free trial.

The admin covers 20 languages including Japanese. Per the developer's documentation, installation is via a theme app extension App Embed, with three placement modes: inline link, floating button, and dropdown. Note that the App Store data access section lists "Online Store script tags, theme" (as it does for ESC), so the developer's description and the App Store listing don't fully agree. If uninstall residue matters to you, confirm this first. Assignment rules cover products, collections, and tags, with a "chart priority" setting to resolve overlaps.

One caveat: there are three 1-star reviews (2021, 2023, 2024), and the December 2023 one alleges that the developer asks merchants to post 5-star reviews after resolving issues. The developer has published a reply denying this. Both the claim and the rebuttal are on the record; neither can be treated as established fact.

CSC: Size Chart & Size Guide

Launched January 29, 2020; 93 reviews; Built for Shopify. Notably, zero 1-star and zero 2-star reviews (one 3-star).

The free plan allows two published charts — the fewest here — but carries no watermark and includes a Done For You Setup. Paid tiers: Grow $6.99/month (unlimited charts, country-based chart switching, import/export, automatic unit conversion), Advanced $14.99/month (500 AI recommendations, multi-language), Plus from $29.99 (order-volume-based). No annual pricing offered.

Implementation is the clearest of the group. The changelog publicly records "Added Theme App Extension Requirement" and "Remove Assets API Support," confirming the app doesn't write into theme code. CSC is the only app in this comparison that publishes this. The admin covers 21 languages including Japanese.

Kiwi Size Chart & Recommender

The largest install base at 1,118 reviews — but no Built for Shopify badge, and 26 one-star reviews, the highest absolute count here (2% of its total; ESC's 7% is the higher proportion). The negatives cluster in 2026.

They fall into three themes.

On pricing changes: an August 22, 2026 review states that $6.99/month once allowed 100 published charts, and $7.99 now allows ten, with order-volume charges added on top. An August 4, 2026 review describes accidentally upgrading, being moved onto the order-volume model, and going from $5–7/month to roughly $150 — adding that having built over 100 charts makes migrating to another app extremely difficult.

On translation: a July 1, 2026 review reports that despite marketing "translate your size charts and recommenders," only buttons and headers are translated. The chart contents are not, Shopify's native Translate & Adapt can't reach them, and support confirmed that locale-specific size guides aren't possible. If you run a multilingual store, verify this before committing.

On data portability: an April 25, 2026 review (roughly four years of use) reports being refused an export of created data. The developer's published reply states that "a full export feature isn't available yet." The absence of a complete export is acknowledged by the developer.

Note also that the free plan's template count is listed as 22 on the App Store and 11 on the developer's own site.

ESC Size Charts

Launched August 2, 2016 — the oldest here. There's a single paid tier, Premium at $4.99/month, which makes charts unlimited. Cheapest paid tier with no chart limit is a clear strength. Seven-day free trial; no annual pricing.

Its targeting is the most flexible of the group, covering five axes: tags, collections, products, vendors, and product types. Implementation uses Online Store 2.0 app blocks.

Against that: 4.1 with eight 1-star reviews (7%) is the weakest rating among the four apps here with triple-digit review counts, and the complaints concentrate on support responsiveness. August 6, 2026: "worked perfectly for over four years, then stopped; emailed support, no reply." June 29, 2026: "emailed support, no reply, waste of time." June 25, 2024: "couldn't export size charts, and no reply from support."

English-only admin. Unit switching and multi-language support aren't mentioned on the listing and couldn't be confirmed.

K: Size Charts & Size Guide, and Quick Size Chart & Size Guide

Neither has enough evidence behind it to recommend for production right now.

K: Size Charts & Size Guide launched October 2, 2024 and rates 5.0 — across 11 reviews, two of which come from merchants who used it for "about 1 hour" and "about 8 hours." Pricing is "Free to install" plus "Growth $1/month" (usage-based, capped at $9.99/month), with the feature lists for both tiers identical. The listing simultaneously claims "unlimited size charts" and "free for development stores," which makes it impossible to tell from the listing what a production store gets on the free plan.

Quick Size Chart & Size Guide is entirely free but has one review, rated 2.0. That review (August 15, 2025) reports that after enabling a chart it didn't appear on the product page, and no setting could be found for where to place the size chart button.

"5.0 so it must be safe" only holds if you read the review count and usage duration alongside it.

The problem with size charts as images

Pasting the chart as a single image is quick, but it creates two issues.

Screen readers can't read numbers inside an image. All they can convey is the alt text, and Shopify's accessibility guidelines recommend keeping alt text within 125 characters. Compressing an entire size table into that is not realistic.

The same guidelines set a minimum body font size equivalent to 16px and a body contrast ratio of at least 4.5:1. Whether an existing chart image meets those thresholds isn't something the theme can control, precisely because it's an image.

Pre-install checklist

1. Does one chart serve every product? If so, skip the app entirely
2. Do you need variant-level switching? (No official native method was found)
3. Does the free plan apply a watermark? Is it shippable?
4. Does the free plan's chart count cover your product categories?
5. Do the upper tiers add order-volume charges? What's the monthly cost after growth?
6. For multilingual stores: does translation cover buttons and headers only, or the chart contents?
7. Can you export what you create? Can you migrate to another app?
8. Is it built on a theme app extension (app block or app embed)?
9. Do you plan to switch published themes? Apps aren't active by default on a new theme
10. Have you checked review count and usage duration? A 5.0 across eleven reviews isn't a signal

Where this leaves you

Work through it in this order.

Check whether Shopify's official pop-up method covers you. One shared chart across all products, and you're done — no app needed.

Then test your catalog against the "one page per product" constraint. If it fails there, that's when app evaluation begins.

Compare free plans on watermarks, not chart counts. CSC states watermark-free outright; Kiwi and ESC state that watermarks apply; MP makes no statement at all and needs a direct question to the developer.

Finally, calculate the cost after growth. Whether an app adds order-volume charges as your order count rises is something to confirm before installing — Kiwi's reviews contain multiple accounts of merchants discovering it after migration had already become difficult.

All pricing, ratings, and review counts in this article were confirmed on each app's Shopify App Store page on September 1, 2026. App Store pricing changes without notice — check the current listing before you install.
