Sell by the meter, m², or cut size — at the exact price.

Metercart lets your customers enter their own measurements on the product page. The price updates live as they type, and the item is added to the cart at the precisely calculated price — with the dimensions carried all the way to the order, email, and packing slip.

5-minute setup · no code · Free plan with every feature

From install to selling by the meter in three steps.

A guided wizard takes you from install to a working calculator on a real product. No theme code, no copy-paste snippets.

Pick what you sell

Start from a template — fabric, wallpaper, flooring, curtains, glass, or a blinds price grid — or build your own.

2

Set your price

Price per meter or m², a formula, or a width × drop grid. A live preview shows the exact price as you configure it.

3

Add the block

Drop the Metercart block onto your product page in the theme editor and assign your products. Done.

Questions, answered.

Do I need to touch theme code?

No. Metercart is a native Online Store 2.0 app block — you add it in the theme editor and it works on any modern theme, including every free Shopify theme.

How does the price reach the cart exactly?

The price is recomputed and validated on our servers before anything is added to the cart, so the line total always matches the measured price to the cent. Customer input is never trusted blindly.

Will it match my store's design?

Yes — the widget inherits your theme's font, corner radius, and button colors automatically, and you can override colors, labels, and even add custom CSS per calculator.

What languages does it support?

The storefront widget ships in English, German, French, Italian, Spanish, Polish, and Czech, picked from your storefront language. Every string is overridable.

Is there a free plan?

Yes. Free includes one calculator and five assigned products with every feature unlocked. Pro at $9.99/month removes the limits and the widget badge.
