Pricing (2026)
✓ Pricing re-verified 1 Sep 2026
Four tiers, and the interesting line is not the price but the sentence under it. Free publishes up to three size charts with 22 templates and unlimited CSV import, and puts a Kiwi watermark on your storefront. Premium is $7.99 a month for up to ten charts, removes the watermark, adds Google Analytics and auto-translation into English and Spanish, and states plainly: no additional monthly charges.
Plus, the tier the store marks Popular, is $14.99 for up to twenty charts, ten size recommenders and six languages. Ultimate is $26.99 for unlimited charts and recommenders and 22 languages. Both Plus and Ultimate carry the same caveat that Premium does not: additional charges apply based on order volume, and the listing does not say what those charges are. Import credits are an optional add-on on every paid tier, and all three come with a 14-day free trial.
So the cheapest paid plan is the only one whose bill you can predict, and the one the store pushes is not. Plans change — always verify the live price on their site.
What the pricing page doesn’t say
Three charts is generous for a small catalogue; the real limit is the Kiwi watermark sitting on your storefront, and removing it is what the $7.99 buys. Judge the free tier on whether you can live with that watermark in front of customers, not on how many charts you get. And read the small print above Plus and Ultimate before you upgrade: both add order-volume charges that the App Store listing never quantifies, while Premium says in writing that it has none.
What Kiwi Sizing does
Shopify size charts and AI fit recommendations, built to cut returns. Free plan carries a Kiwi watermark; Premium is $7.99 a month and the only paid tier without order-volume charges. From Staytuned.
When the paid plan is worth it
The step that matters is Free to Premium at $7.99, and it buys two things: your storefront stops carrying someone else's watermark, and the bill stays flat no matter how much you sell. Everything above that trades predictability for capacity. Plus at $14.99 doubles the charts and adds the size recommender with its analytics, which is the actual product for a fashion store — but it also switches you onto order-volume charges that are not published anywhere on the listing.
If your catalogue fits in ten charts, staying on Premium is worth real money at scale, because it is the only tier where growth in orders does not move the invoice.
How to actually use Kiwi Sizing
Install on free and publish one chart on your worst-returning product, not your best-selling one — that is where a size chart pays for itself and where you can measure it. Look at your own storefront on mobile and decide whether the watermark is acceptable; that decision, not the chart count, is what moves you to Premium. Only look at Plus once you actually want the AI recommender, and when you do, ask support what the order-volume charge is before you switch — it is not on the listing.
Kiwi Sizing vs Fast Bundle, side by side
Both columns come from the same place: each vendor’s own published pricing, read on the date shown in the sources at the foot of this page. We do not average them into a score.
Both names above are affiliate links: we may earn a commission if you sign up, at no extra cost to you. Neither changes what this table says: both columns come straight from the vendors’ own pricing pages.
The natural comparison is Fast Bundle or the native Shopify size guide — the alternatives are a general merchandising app or building the chart into your theme — Kiwi earns its place when the recommender, not the chart, is what you are after.

Frequently asked questions
What should I weigh before buying E-commerce software?
Check your platform and version specifically. Shopify support is close to universal in this category, while WooCommerce, BigCommerce, Magento and headless setups vary a lot, and 'supported' sometimes means a generic API rather than a maintained app. A listing in your own platform's app store, with recent reviews there, is a better signal than the vendor's logo wall.
