10 Best Shopify Size Chart Apps of 2026

MP Size Chart & Size Guide, from the developer Shopplaza, ranks first because it pairs a large feature set with low prices and the strongest review record in the category. The free Starter plan publishes up to 3 size charts, assigns them by product, and includes 30+ templates, automatic unit conversion, a size guide page, chart imports and AI size recommendations. Growth at $6.95 a month raises the limit to 10 charts, adds auto-translation, advanced chart assignment and Google Analytics, and allows up to 800 AI recommendations. Pro at $12.95 a month removes the chart limit and covers up to 2,000 AI recommendations, while Advanced at $24.95 a month raises that to 5,000 and adds priority support. The listing names 20 languages and integrations with Foxify, langify and Transcy, and it offers to migrate charts from another app for free. The main thing to watch is the AI recommendation allowance, which scales with the plan rather than with store traffic.

Kiwi Size Chart & Recommender, built by Staytuned, has the largest review base among Shopify size chart apps in this list, with 1,245 reviews at a 4.7 rating when we checked. The free plan publishes up to 3 charts, uses 22 pre-built templates and allows unlimited chart uploads by CSV or import from product descriptions, but it carries a Kiwi watermark. Premium at $7.99 a month raises the limit to 10 charts, removes the watermark, adds Google Analytics and auto-translates charts into English and Spanish, with no additional monthly charges. Plus at $14.99 a month adds up to 10 custom size recommenders, recommender analytics and six translation languages, and Ultimate at $26.99 a month removes all chart and recommender limits. Kiwi drops a place on value: its recommender plans list extra charges based on order volume, so the bill rises with sales, while MP Size Chart includes AI recommendations on its free plan.

Smart Size Chart & Size Guide is a size chart and fit quiz app from SmartSize, a developer based in Nuernberg, Germany, rated 4.9 from 151 reviews when we checked. Its free plan covers 2 charts with pre-made templates for men, women, kids and pets, AI chart creation from an image, automatic unit conversion and international sizing, and it does not add a watermark. Starter at $9 a month raises the limit to 10 charts and adds multi-tab charts, a true-to-size fit scale, AI translations and priority support, and Growth at $12 a month removes the chart limit. Pro 100 at $19 a month adds the AI Find my size quiz for 100 users a month, with fit finders for men, women, kids and pets and AI plus rule-based matching. The listing names 25+ languages and an MCP connection for AI assistants. Smart Size Chart ranks third because its entry price is higher than the two apps above it and the fit quiz sits on a usage-capped tier.

BF Size Chart & Size Guide, from Relentless Apps and previously called Best Fit Size Charts, is a plain size chart builder priced by chart count. The free Basic plan creates 3 charts that can connect to unlimited products, with cm and inch conversion, custom text boxes, uploaded images and measurement guides, and it lists no Powered by watermark. Starter at $2.99 a month raises the limit to 10 charts and adds link placement next to the size label, multiple charts per product and chart export and import. Premium at $5.99 a month allows up to 100 charts and Unlimited at $11.99 a month removes the cap, and all paid plans are free for development stores. The listing covers apparel, shoe and ring size charts and integrations with Vajro and VO Product Options. It ranks fourth because it lists no size recommender or fit quiz, so it suits stores that only need clear tables.

Goodchart Size Chart & Guide, from the Australian developer Goodsize, treats the size chart as a place to sell. Its free plan creates conversion and table charts, adds an Add to Cart button inside the chart, lets you upload designs or use templates, includes an analytics dashboard and has a size recommender toggle. Growth at $4.99 a month expands chart coverage and adds an AI size recommender, data import for faster chart creation, an advanced analytics dashboard and a Notify Me tool for out-of-stock items. Pro at $9.99 a month covers unlimited charts, AI recommendations for high-traffic stores, more Notify Me slots and dedicated onboarding. The listing names 9 languages and integrations with Klaviyo and Mailchimp. Goodchart ranks fifth because it had only 9 reviews at check time and the listing does not give exact chart limits for the Free and Growth plans, which makes plan sizing harder than with chart-count apps.

Pavo Size Chart & Size Guide, from Zifyapps, is the cheapest way in this list to publish unlimited size charts. Every plan lists the same features: ready-made templates you can clone, display rules by collection, product, tag, vendor and product type, analytics and a choice of popup or inline charts. The only difference between plans is the chart count: the free plan allows 1 chart, Pro at $1.99 a month allows 5 and Unlimited at $2.99 a month removes the limit. Tables can be pasted from Google Sheets, Google Docs or Microsoft Excel, which helps stores moving charts from spreadsheets. The listing shows 4.7 from 31 reviews, and paid plans come with a 3-day trial. Pavo ranks sixth because it lists no size recommender, fit quiz, unit conversion or translation features, so it covers the basics only.

Fit Find is a newer app, launched on the Shopify App Store on June 8, 2026, that focuses on size recommendations rather than chart design. It adds a Find my size button to product pages and asks shoppers four questions: height, weight, build and fit preference. At install it scans the catalog and reads existing size charts, including charts inside product images, and the merchant reviews everything before it goes live. Pricing is tied to results: the free plan has no monthly fee and charges $0.02 per order where a shopper used the size finder, with a Powered by FitFind badge, while FitFind Pro costs $9.99 a month plus $0.01 per attributed order and removes the badge. Both plans list unlimited size recommendations and reporting on attributed orders and estimated returns avoided. Fit Find ranks seventh because it had 4 reviews at check time and offers fewer chart layout options than the apps above it.

Sized Size Charts & Size Guide, from NexusMedia, is aimed at stores that want size guides with more than a table. The free plan publishes 2 charts with 3 pre-built designs, 14 basic templates, inline, pop-up or sidebar placement, assignment by product or collection and a built-in image editor for adding text and arrows to measurement images. Growth at $9.99 a month raises the limit to 10 charts and adds unlimited tabs, tables, images and videos, 20+ templates, assignment by tags, vendors and types, and multilingual support. Premium at $19.99 a month adds a custom design service and priority support, and annual billing saves 30%. Sized ranks eighth because $9.99 a month for 10 charts is expensive next to BF Size Chart's 100 charts for $5.99, and the listing had 8 reviews at a 4.0 rating at check time.

True Fit is the enterprise option in this list. Instead of building charts, it brings AI size and fit guidance to the product page: an AI shopping agent answers questions about fit, fabric and style, and personalized size recommendations draw on real-world fit data that combines product, shopper, purchase and return information. The single True Fit Standard plan costs $1,000 a month and covers up to 150k annual orders, with agentic and form-based size recommendations, on-demand insight reporting, a knowledge base and access to customer success and support. The listing names integrations with Loop Returns, Tapcart and Shopify Checkout. It had 23 reviews at a 4.5 rating at check time. True Fit ranks ninth on this site's weights because value counts for 35% of the score, and at $1,000 a month it costs more than a year of the most expensive plan of any other app here.

ESC Size Charts, from the UK agency Eastside Co, is one of the oldest size chart apps on the Shopify App Store, listed since August 2, 2016. Its feature set is simple. The free Basic plan creates up to 3 charts with text and images and shows an ESC watermark, and Premium at $4.99 a month allows unlimited charts, removes the watermark and adds import and export. Charts can be assigned by tags, collections, products, vendors or product type, or shown storewide, and the app supports Shopify 2.0 app blocks. It ranks last because its rating had fallen to 3.3 from 138 reviews at check time, and a review dated October 2, 2026 reports that charts stopped showing and that emails, chats and calls went unanswered. Stores already using it should keep an export of their charts, and new stores get unlimited charts for less from Pavo.
