Customizing Product Pages in Squarespace
Product Image Layout
Product images are the most important element on any e-commerce page. Squarespace lets you configure image layout, zoom behavior, and gallery style through the product page editor. Use high-resolution images (at least 1500 pixels on the longest side) and upload multiple angles for each product. Configure the image gallery to display thumbnails below or beside the main image depending on your template.
For advanced image customization - like changing the zoom magnification, adding image borders, or adjusting gallery spacing - use Custom CSS. Target the product image container with selectors like .ProductItem-gallery and adjust properties to match your design. For a complete CSS walkthrough, our guide to adding custom CSS to Squarespace covers how to find and target product page elements.
Product Description and Details
Write product descriptions that address the customer's questions before they ask. Include materials, dimensions, care instructions, and use cases. Squarespace supports rich text formatting in product descriptions - use headings, bullet lists, and bold text to make key information scannable.
For products with multiple specifications, use the Additional Info section in the product editor. This adds collapsible detail sections below the main description - a clean way to present technical specs without cluttering the primary description area.
Product Variants and Options
Configure size, color, material, and other variant options in the product editor. Squarespace supports dropdown menus and button-style selectors for variants. If you need custom option types or conditional logic (showing different options based on previous selections), you will need custom JavaScript through Code Injection.

Customizing the Squarespace Checkout Experience
Checkout Page Settings
Go to Commerce > Checkout in your Squarespace dashboard to configure the checkout experience. You can customize which information fields appear (phone number, company name, special instructions), whether to offer gift wrapping or order notes, and how shipping options display. Every unnecessary field you remove from checkout reduces friction and increases completion rates.
Express Checkout Options
Squarespace Commerce Advanced supports express checkout through Apple Pay, Google Pay, and Afterpay/Clearpay. Enabling these options gives customers one-click checkout on supported devices, which significantly reduces cart abandonment on mobile. Configure express checkout under Commerce > Payments.
Checkout CSS Customization
The Squarespace checkout page has limited built-in customization, but you can modify its appearance using the Order Confirmation Code Injection field and Custom CSS. Adjust button colors, form field styling, and typography to match your brand. For detailed checkout styling techniques, our guide to customizing Squarespace checkout covers every available option.
Customizing Shipping and Tax Settings
Shipping Rules
Configure shipping rates under Commerce > Shipping. Squarespace supports flat-rate shipping, weight-based shipping, and carrier-calculated rates (on Commerce Advanced). Set up shipping zones for different regions and create free shipping thresholds to incentivize larger orders. Free shipping above a specific order value is one of the most effective conversion tactics in e-commerce.
Tax Configuration
Set up tax rates under Commerce > Taxes. Squarespace supports automatic tax calculation for US-based stores and manual tax rate configuration for international stores. For complex tax scenarios, consider integrating a tax extension like TaxJar through the Squarespace Extensions marketplace.
Customizing Order Emails and Notifications
Squarespace sends automated emails for order confirmation, shipping notification, and refund confirmation. Customize these under Commerce > Customer Notifications. You can edit the email subject lines, body text, and include your brand voice. Add your logo, adjust colors, and write copy that reinforces your brand personality - order confirmation emails have some of the highest open rates of any email type.
For advanced email customization beyond what the built-in editor supports, connect an email marketing platform like Mailchimp or Klaviyo through the Extensions marketplace. These tools give you full control over post-purchase email sequences including review requests, upsell campaigns, and loyalty program invitations. For email strategy, our Squarespace SEO guide covers how email engagement supports your overall digital presence.
Customizing Store Layout and Navigation
Store Page Layout
The store page layout determines how products display in your catalog view - grid, list, or masonry. Configure the number of columns, image aspect ratio, and how much product information appears in the grid (title, price, quick add button). A clean grid with consistent image sizes and minimal text creates the most professional impression.
Category and Filter Navigation
Organize products into categories and enable category filters on your store page. This lets customers browse by product type without scrolling through your entire catalog. On Commerce Advanced, you can also enable price and variant filters. Clear category structure is essential once you have more than fifteen to twenty products.
Related Products and Upsells
Squarespace can display related products below the main product detail section. Configure this under Commerce > Product Page to show products from the same category or manually curated recommendations. Related products increase average order value by surfacing items the customer might not have found through browsing. For layout strategies that maximize conversions, our Squarespace design tips guide covers product page hierarchy and visual flow.
Advanced E-Commerce Customization with Code
Custom Product Page Elements
Use Code Blocks to add custom elements to product pages - size charts, material comparison tables, trust badges, or countdown timers for limited-time offers. Place the Code Block in the product description area or in a section below the product details.
Custom Cart and Checkout Behavior
JavaScript through Code Injection can modify cart behavior - adding minimum order requirements, displaying promotional messages based on cart value, or implementing custom upsell popups. These modifications require coding knowledge and careful testing. For implementation guidance, our guide to adding custom code to Squarespace covers code injection best practices.
Third-Party E-Commerce Extensions
The Squarespace Extensions marketplace includes tools for shipping (ShipStation, Shippo), reviews (Judge.me, Yotpo), accounting (QuickBooks, Xero), and print-on-demand (Printful, Printify). Each extension adds specialized functionality that Squarespace Commerce does not include natively. For a complete overview, our guide to customizing your Squarespace website covers the extensions ecosystem.
