Why merchants install it
What changes in your store
01
Exact amounts, not packs
Sell 2.5 m of fabric or 1.25 kg of coffee instead of forcing shoppers into fixed packs or a long list of variants.
02
One price everywhere
The price shoppers see on the product page is the price Shopify charges. No draft orders, no hidden discounts, no price overrides.
03
Stock that adds up
Stock is counted in your steps, so 50 m of fabric sold in 10 cm steps is 500 in stock and never oversells.
Features
Everything in Sell by Measure
Measure input with live price
A theme block replaces the quantity selector on products sold by measure: "2.5 m = $30.00" as the shopper types.
17 units
kg, g, lb, oz, m, cm, mm, yd, ft, in, m², sq ft, L, ml, m³, gal and fl oz.
Rules per product
Smallest step, minimum, maximum, default amount and quick amount buttons such as 1, 2.5 and 5.
Shopify unit price
The app turns on Shopify's own unit price, so "$12.00 / m" shows in the cart, at checkout and on the order.
Checkout check
A checkout rule refuses amounts below the minimum or above the maximum, even if the cart was edited by hand.
Length × width (Pro)
For flooring, glass or turf: shoppers enter the room size and the app sells the exact area.
Fast storefront
The block loads from Shopify's CDN as a theme app extension. Our server is never in the shopper's path.
Every Shopify plan
No Shopify Plus features. Works in Online Store 2.0 themes such as Dawn and Horizon.
How it works
Live in four steps
Pick a product
In the app choose a product, the unit (for example metres), the step (0.1 m) and the price per unit ($12.00 / m).
Add the block
Click "Open theme editor" and add the Measure input block to your product template. Save.
Turn on the checkout check
One click adds the checkout rule that enforces your minimum and maximum amounts.
Sell
A shopper asks for 2.5 m: the cart holds 25 steps of 10 cm and Shopify charges 25 × $1.20 = $30.00.

Does it work on the Basic Shopify plan?
Yes, on every plan. The app uses no Shopify Plus features.
Why does the cart show 25 for 2.5 m?
The product is sold in steps, for example 10 cm. 25 steps are 2.5 m. The variant name ("10 cm") and the unit price ($12.00 / m) make this clear in the cart, at checkout and on the order.
Can shoppers change the amount in the cart?
Yes. The cart quantity is the number of steps, so any change is still an exact amount. The checkout check enforces your minimum and maximum.
Does stock work?
Yes. Stock is counted in steps (50 m with a 10 cm step is 500 in stock). When overselling is off, shoppers cannot ask for more than is left.
Do discounts, taxes and currencies work?
Yes. Shopify prices each step like any other item, so all Shopify features work as usual.
What happens when I uninstall?
The block leaves your theme and the checkout check turns off. Variant prices and unit prices stay as normal Shopify prices.
Which themes are supported?
Online Store 2.0 themes that support app blocks on the product page, such as Dawn and Horizon.
