Checkout Field Order: The Sequence That Costs You Completions

Baymard Institute's checkout benchmark, built from 16 years of usability testing across 327 top-grossing US and EU sites, puts the average US checkout at 23.48 form elements shown by default, against an ideal of 12 to 14. Count only the fields shoppers type into and the average is 14.88, against an ideal of 7 to 8. The average documented cart abandonment rate across 50 studies is 70.22 percent, and 17 percent of US shoppers have abandoned an order because the checkout felt too long or complicated.

The same research says better checkout design can lift a large site's conversion rate by 35.26 percent. The field cut is the cheapest part of that lift, because it is a deletion, not a build. Every field you remove is a field that cannot be mistyped, cannot fail validation, and cannot make a shopper on a phone give up.

23.48 elements against an ideal 12 to 14

Email goes first for three reasons, and only one of them is the receipt. It is the recovery address for an abandoned cart, it is the account identifier if the shopper creates one, and it is the field the shopper can complete fastest, which gets them committed to the flow. A checkout that asks for the shipping address before the email is asking the shopper to do the hard part before the easy part.

Shipping address comes second, then the shipping method, then payment. That order follows the shopper's mental model: where is it going, how fast, and how do I pay. Payment last is not a courtesy, it is a conversion decision. By the time the shopper reaches the card field, they have already invested in the order, and the sunk cost works in your favour.

Email first, because everything else hangs off it

Company name goes first, unless you sell to businesses. Address line two becomes optional, never required; a shopper who needs it will fill it, and a shopper who does not will not be blocked by it. Phone goes unless the carrier needs it for delivery, and if the carrier does need it, say so next to the field, because a shopper who knows why will give it.

The gift message belongs at the end, after payment, not in the middle of the address form. A field in the wrong step is worse than a missing field, because it interrupts the flow at the exact moment the shopper is deciding whether to continue. Cut five fields this week and watch the completion rate, not the time on page.

The fields to cut this week

Change the field order and the field count together, run it for a week, and compare the completion rate against the previous week. Do not compare time on page, because a shorter checkout should take less time, and time on page will fall whether the change worked or not. The metric that matters is completed purchases divided by checkouts started.

The test is one week of completions

A negative result is still a result. If cutting five fields changes nothing, the fields were not the problem, and the problem is the shipping cost, the account prompt, or the total that appears too late. Say so in the test notes and move on to the next candidate. A test with no failed hypothesis in it is a report, not a test.

Frequently asked questions

How many form fields should a checkout have?

Baymard's testing says 12 to 14 form elements, or 7 to 8 if you count only the fields shoppers type into. The average US checkout shows 23.48.

What order should checkout fields be in?

Email, shipping address, shipping method, then payment. The order follows the shopper's mental model: where it is going, how fast, and how to pay.

Which checkout fields can I remove?

Company name, a required address line two, phone unless the carrier needs it, and anything that does not change fulfillment or the charge.

Does cutting fields actually lift conversion?

Baymard estimates better checkout design can lift a large site's conversion by 35.26 percent, and the field cut is the cheapest part of that lift.
