Product variant calculator. Count every combination your options make.

List your product's options and their values to see instantly how many variants they combine into, and what that means for photography and for a 3D configurator.

01— Method

How to count product variants

Multiply the number of values of every option the buyer chooses. Five steps, and what this calculator does with each.

  1. 01List every option the buyer chooses

    Size, color, material, finish, hardware: every choice that makes one sellable product different from another. Leave out choices that do not change what ships, like gift wrap.

    This tool: one row per option, up to 30.

  2. 02Count the values of each option

    Write the values out where you can, so nothing is counted twice. Where you only know the number (a 40-color fabric range), the number is enough.

    This tool: type the values separated by commas (a repeat counts once) or switch the row to a count.

  3. 03Multiply the counts

    Every value of one option can pair with every value of the others, so the variants are the counts multiplied together, not added. Five options of 4, 20, 3, 2 and 5 values make 2,400 variants.

    This tool: multiplies them exactly, however large the result.

  4. 04Take out the combinations you do not sell

    Some pairs are never offered: a finish only on one size, a fabric not available on the corner unit. Each rule removes its own share.

    This tool: one optional percentage you estimate; it does not model individual rules.

  5. 05Decide what each variant needs

    A photographed catalog needs every variant shot from every angle. A 3D configurator builds each option value once and assembles the variant on screen.

    This tool: photos are variants × angles per variant; the configurator side counts the option values.

02— Photos or 3D

Why a configurator beats photographing every variant

Photography grows with the number of variants; a configurator grows with the number of option values. The gap widens with every option you add.

Photos grow by multiplication
Add one 10-color option and the photo count is ten times what it was. Every new option multiplies the shoot, the retouching and the files to manage.
A configurator grows by addition
The same 10 colors add 10 materials to a 3D model. Each option value is modeled once, and every combination is drawn from those parts when the buyer picks it.
Not every value is equal work
A color or a finish is a material swap. A value that changes the shape, like an arm style, needs its own 3D part, and a size that stretches every part may need a parametric model. The count is a starting point for a quote, not the quote.

What a configurator build costs: see pricing.

03— FAQ

Questions about the product variant calculator.

What it does, what it leaves to you, and what it costs.

Multiply the number of values of every option. A sofa in 4 sizes, 20 fabric colors, 3 leg finishes, 2 cushion fills and 5 arm styles has 4 × 20 × 3 × 2 × 5 = 2,400 variants. This calculator does the multiplication for you, exactly, from the options you list.

No. The calculator runs in your browser and sends nothing. Your options are written into the page address so you can share or bookmark the result; anyone you send that link to sees your option names and values.

Prices, unless you type your own cost per photo: the calculator never guesses one. It also leaves out retouching, styling, renders, lifestyle shots, SKU and inventory management, and the rules between specific options; the only exclusion it models is the one percentage you enter.

Roughly, and that is the point of the comparison, but it is not a quote. Colors and finishes are material swaps on one model. Options that change the shape need a 3D part each, and sizes that stretch every part may need a parametric model. Book a call if you want a real count for your catalog.

Enter the share you do not sell as a percentage. The calculator takes it off the variant count before counting photos, rounded to the nearest whole variant. It is your estimate; the calculator does not know your rules.

Any. Counts are kept as exact whole numbers, so 30 options of a thousand values each still multiply without rounding. Past a quadrillion (10^15) it says "more than a quadrillion", because the exact digits stop meaning anything.

Yes. No sign-up, no email and no limit on how often you use it.

Too many variants to photograph?

A 3D configurator models each option value once and shows the buyer the exact combination they pick, priced. We build them for made-to-order manufacturers. See configurator demos by industry.
