Squarespace Commerce for Fashion Designers: Limits to Know

The main Squarespace Commerce limits for fashion designers are the number of variants per product, which plans allow custom code, and transaction fees on the lowest plan. For a small, well-edited collection these limits rarely matter. They start to matter when you sell many sizes and colors, or want to add outside tools such as a sizing widget.

All facts below come from Squarespace's own pages, checked November 2026. If you plan to add sizing or try-on later, the guide to virtual try-on for WooCommerce and other platforms shows how non-Shopify stores usually do it.

How many variants can a Squarespace product have?

Squarespace's help center says each product can have up to six options and 250 variant combinations, images and SKUs, as stated in its guide to adding product variants.

An option is something like Size or Color. A variant is one combination, such as "Black, size 10."

Here is how to check your own products against the cap:

1. Count the values for each option. For example, 6 colors and 8 sizes.
2. Multiply them: 6 × 8 gives 48 variants.
3. Compare the result with the 250 limit.

A dress in many colors and sizes fits easily. A product with three options, such as size, color and length, can grow quickly, so do the multiplication first.

Which plans let you add custom code?

This matters because most sizing tools, reviews apps and widgets need a script on your product pages. Squarespace's pricing page lists four plans: Basic, Core, Plus and Advanced. It shows code injection and code blocks as not included on Basic and included on Core, Plus and Advanced.

So if you want to paste in a third-party script, plan for a plan above Basic. Check the pricing page for what is current when you buy.

What do fees look like on each plan?

The same Squarespace pricing page lists a 2% online store transaction fee on Basic and 0% on Core, Plus and Advanced. It also lists standard card rates of 2.9% + $0.30 on Basic and Core, 2.7% + $0.30 on Plus and 2.5% + $0.30 on Advanced.

These are payment-processing and platform fees, not a verdict on the platform. For a designer selling a few high-price pieces, the fee is small. For high volume at low prices, run the math.

What does Squarespace not do for fashion by default?

Squarespace gives you product pages, variants and checkout. Fashion stores often also need:

• A size recommendation. Variants list sizes, but they don't tell a shopper which one fits.
• A try-on view. Photos on models don't show the garment on the shopper.
• Per-garment size charts that follow the fit of each piece.

These can be added through a script, which is why the code-access point above matters. The guide to Squarespace vs Wix for fashion designers compares how both builders handle this, and choosing a website builder as a fashion designer covers the wider decision.

How can you add sizing to a Squarespace store?

ZeDaq.ai offers a script-tag widget for Squarespace, WooCommerce, Wix, BigCommerce and custom sites. You paste one script into the product template:

<script src="https://www.zedaq.ai/widget/zedaq.js" data-key="…" defer>

The key must be locked to your store's domain in Dashboard → API keys. The widget adds "Try it on" and "Find my size." Setup details are in the widget documentation.

You enter your own size charts in the dashboard, one per garment type. The scan then recommends your labels. Test the result on a real product page, since placement depends on your template.

What can you do if a product hits the variant cap?

If a product needs more combinations than the cap allows, you have two practical choices.

• Split the product. Make one product per color, each with its own size options. This also lets each color have its own photos.
• Cut an option. Drop an option you rarely sell, such as a length that only a few customers choose.

Splitting is the usual fix for fashion, because shoppers look for a color first. The trade-off is more product pages to manage and keep consistent.

What should you check before you build?

Run through this list before you pick a plan.

1. Multiply your options for your largest product and compare with the cap.
2. Decide whether you need a third-party script, and choose a plan that allows code.
3. Work out the transaction and card fees for your expected order value.
4. Write down which fit tools you want, such as size charts and a size recommendation.
5. Test a sample product page on your phone before you add the whole collection.

Because limits and prices can change, confirm each one on Squarespace's pages on the day you buy.

Is Squarespace right for you?

It is a reasonable fit if you have a small collection, a design-led site and limited variant combinations. Look at other options if you need very large catalogs or heavy customization.

If you have a developer and want a custom experience, the try-on API for developers is the other route.

FAQs

Is Squarespace good for selling clothing?

It can be, for small collections and brand-led sites. Check the variant cap and code access against what you plan to sell.

Can I add a size recommendation to Squarespace?

Yes, on a plan that allows code injection. Paste a widget script into the product template and test it on a live page.

Do Squarespace limits change?

They can. Always confirm the current numbers on Squarespace's own help center and pricing page before you commit.

Does Squarespace work with an API?

Squarespace itself isn't the API here. A try-on or sizing service exposes its own API, and a developer can call it from your site.
