How to Customize the WooCommerce Cart Page for Beginners

The default WooCommerce cart page works, but it rarely matches the rest of a store’s design — the spacing feels off, the coupon field looks like an afterthought, and there’s no nudge toward the next step in checkout. Left untouched, it’s the page most likely to make a store feel unfinished even after everything else has been polished. In most stores I build, the cart page gets more attention than owners expect it to need, because it’s the last stop before checkout — small friction here costs real sales, and the numbers back that up more than most store owners realise.

What’s Actually at Stake on This Page

Cart abandonment is already one of the biggest revenue leaks in ecommerce — the Baymard Institute’s ongoing analysis across 50 separate studies puts the average abandonment rate at just over 70%, meaning roughly seven of every ten shoppers who add something to a cart leave without buying. The rate isn’t evenly spread: mobile abandonment runs close to 86%, against about 73% on desktop, which is worth knowing before assuming a cart page that looks fine on a laptop is actually fine. Baymard’s checkout-usability research also finds that a typical large ecommerce site can recover a meaningful share of that lost revenue through better checkout design alone — and separately, nearly half of abandoners cite shipping fees, taxes, or other charges making the total higher than expected as the specific reason they left. Both findings point at exactly the page this guide covers: a cluttered or confusing cart page doesn’t cause all of that abandonment, but it makes an already-leaky step measurably worse.

Editing the Page

Go to Pages in wp-admin and open the page marked “Cart” — WooCommerce creates this automatically on install. What you see next depends on the theme:

Block Themes: the Cart Block

Since WooCommerce 8.3 (November 2023), the block-based Cart and Checkout blocks are the default for any new store, and any site running a block theme gets full visual control over the page inside the editor — click into any section (items, coupon form, order summary, checkout button) to adjust colours, spacing, and visibility directly, with no code involved. Rearrange the block’s inner sections so the order summary and checkout button sit clearly above the fold, since that’s what most customers are actually looking for.

Classic Themes: the Shortcode and CSS

Older setups show a page containing only the [woocommerce_cart] shortcode, which pulls the layout from the theme’s template files instead. Styling changes here happen through CSS targeting WooCommerce’s cart table classes — .woocommerce-cart-form, .cart_totals, and .coupon are the main ones. Add custom CSS through Appearance → Customize → Additional CSS rather than editing theme files directly, so a theme update doesn’t wipe out the changes. Full details on the shortcode’s structure and available hooks are in WooCommerce’s own shortcode documentation.

The Changes That Actually Move the Needle

• Cross-sell products. WooCommerce shows these automatically, pulled from the Linked Products tab on each product’s edit screen. Set genuinely complementary products — a phone case cross-sold with a phone converts far better than an unrelated bestseller pushed onto every cart. See adding upsells and cross-sells for setting these up well.
• A visible coupon field. Often the most overlooked element on the default layout — many customers miss it entirely, then abandon the cart to search for a discount code elsewhere. Give it its own visible section with a clear label rather than a collapsed link; if the store runs discounts regularly, this one change alone can noticeably cut abandonment.
• Shipping estimates and trust signals. Enable the shipping calculator so customers see an estimated cost before checkout — surprise shipping fees are, per the Baymard data above, one of the single most common reasons carts get abandoned at the last step. A short line about secure payment or the return policy near the checkout button reassures hesitant buyers without a full trust-badge redesign.
• A visible note about the persistent cart. WooCommerce saves a logged-in customer’s cart between visits by default, which is worth surfacing rather than leaving invisible — a short “Your cart is saved” note near the top reassures customers browsing across multiple sessions that they won’t lose their selections, reducing the pressure to buy immediately or risk starting over.

Practical Tips

• Test the cart page on mobile specifically — the default layout often compresses awkwardly on smaller screens, and given the 86% mobile abandonment figure above, this is where fixes matter most.
• Keep “Proceed to Checkout” visually distinct from “Update Cart” so customers don’t click the wrong one by mistake.
• If a customer abandons anyway, pair this work with abandoned cart recovery to still have a chance at winning the sale back.
• Check the cart page after any theme or WooCommerce update — layout and CSS changes here are more likely to break silently than on standard content pages, since so much of it is generated dynamically.

Common Mistakes

• Editing theme template files directly for CSS-only changes, which then get overwritten on the next theme update.
• Adding too many cross-sell products, which clutters the page and buries the checkout button further down the screen.
• Leaving the shipping calculator disabled, so customers only see shipping costs after committing to checkout — exactly the surprise-cost pattern the abandonment data flags.
• Styling the cart page in isolation without checking it still matches the checkout page that follows it — an inconsistent handoff between the two undermines trust right before payment.

When Block Customization Isn’t Enough

Block-based customization and CSS tweaks cover the vast majority of stores — free, no developer required, and enough to fix the friction points that actually lose sales. A fully custom cart template built with PHP hooks makes sense only for stores with unusual cart logic (subscription bundling, tiered quantity discounts) that the block editor can’t express. Most stores following the step-by-step guide to building a WordPress website won’t need to go beyond block and CSS customization, and pairing it with a clean shop page covers the two pages customers see most before they buy.

A cart page that’s easy to scan, shows shipping costs upfront, and makes the coupon field and checkout button obvious will consistently outperform the untouched default — worth doing given that shipping surprises and clutter are named, specific, measurable reasons real shoppers walk away. Start with layout and coupon visibility; those two changes alone address most of what causes carts to get abandoned.
