Wix price calculator apps compared: service quotes vs. price by size (2026)
Short answer: “price calculator” apps in the Wix App Market do one of two different jobs. Most are estimators for services: a visitor answers questions, sees a price and sends you a request (Price Calculator, Instant Quote Calculator, Quote & Price Calculator, Price Calculator & Quote Form, Calculator). A few are price-by-size calculators for Wix Stores: the shopper types a width, height or length on the product page and the real product goes into the store cart at that price (Price by Size Calculator, and Price Calculator: Custom Size, ours). Pick by what should happen after the price: a lead you follow up, or an order paid at checkout.

Service estimate or price by size?
- You quote jobs (cleaning, moving, painting, web projects): use an estimator. The visitor gets a price range or a figure, you get a lead with the details. Payment happens later, by invoice or booking.
- You sell products cut or made to size (banners, signs, stickers, fabric, flooring, glass, blinds): use a price-by-size calculator. The shopper pays the calculated price at your Wix Stores checkout, with your shipping, tax and discounts, and you get the size on the order. Creating a variant for every size does not scale past a handful of sizes.
What to check in a price-by-size app
- Does the real product go into the cart? Stock, reports and order emails then keep working.
- Is the size on the order (and the packing slip), so you know what to make?
- Units: square meters or feet, linear meters or yards, and whether shoppers can switch units.
- Setup fee, minimum price, rounding and size limits.
- Options: can each material or finish have its own rate?
- Weight for shipping: does the weight follow the size, for weight-based rates?
- Price tiers or formulas for prices that drop with larger areas or depend on letters or volume.
Where Price Calculator: Custom Size fits
Price Calculator: Custom Size is our app, so read this part with that in mind. Shoppers type their size on the product page and see the price as they type, with a line that explains it (“0.72 m² × $18.00 + $8.00 setup”). The store’s own Add to Cart puts the real product in the cart at that price, and the size is shown on cart, checkout and order. Area and Length types, a setup fee, a minimum price, rounding and size limits are free for 1 calculator on up to 3 products. Pro ($9.99 a month, $7.99 billed yearly, 14-day trial) adds up to 100 calculators, Volume and Custom formula types, price tiers by size and weight per size for shipping. It does not collect leads or quote requests; for that, pair it with a quote app or use an estimator above.
More: charge by square foot or square meter, custom-size banners, stickers and signs, made-to-measure fabric, glass, blinds and flooring.
