Options Price Calculator Review 2026: Price by Dimensions

Shopify’s variant system is a grid, and some products are not a grid. If you sell blinds, glass, worktops, fabric, signage or anything cut to size, the honest number of combinations is in the thousands and the variant limit stops you long before you get there. This app sidesteps that: the customer enters dimensions, a formula turns those into a price, and nothing needs to exist as a variant beforehand.

The formula builder is the centre of it. You define fields, a width, a height, a material dropdown, a quantity, and then write the arithmetic, with product metafields available as inputs so a per-square-metre rate can live on the product rather than inside the formula. Price updates in real time as the shopper fills the fields, and the selections carry through to the cart and checkout so the line item shows what was ordered. On Premium, conditional logic lets one choice change what is offered or charged elsewhere, which is the difference between a calculator and a configurator.

For personalised rather than measured products there is a visual side too: fields can be positioned on the product image so the customer sees their name and number on the shirt as they type, with pattern and colour pickers alongside. The option fields are translatable into every language your store runs, which is a real consideration if your custom-products business sells across borders.

The reservations are proportionate rather than alarming. Twenty-six reviews is a thin base, even at a straight 5.0, and the app launched in August 2025, this is not a decade-tested product. The free plan is 20 uses, which is a trial dressed as a plan rather than a tier you can live on. And conditional logic, the feature that most made-to-measure sellers end up needing, is on the $14.99 tier rather than the $9.99 one. Set against that: the Built for Shopify badge, reviews from merchants describing a year of use, and prices that are trivial next to the revenue a cut-to-size product line generates.
