23 Nasty Event Registration Form UX Mistakes (And What You Can Do About Them)

Event Registration Form UX Mistakes.png

Imagine yourself filling out a long and cumbersome form to register for an event. After spending a few minutes finding your credit card (it’s probably upstairs. Why is it always upstairs?) & billing details you click on “Register” only to encounter your form filled with red error messages.

All of a sudden the browser’s “close” button seems much more tempting than before, right?

Despite the constant innovation, web forms, including event registration forms, remain one of the core barriers between registrants and event marketers. 

And any kind of obstacle or filling out the form can lead to frustration which as a result can lead to drop-outs. 

Here are some of the nastiest event registration form UX mistakes and what you can do about them:

Mistake #1: Registration Form Fields Are Too Long For Their Input

The size of an input field should reflect on how much text the user is expected to enter. Fields like post code or house number should be shorter than street address lines (see example below)


Mistake #2: Event Registration Form Fields are not automatically pre-populated


Most modern event registration software can pre-load address fields from Google Maps or pre-populate a registration form with data from your CRM, like HubSpot & Co. 

This will save attendees from entering information that should really already be known to you. 

Mistake #3: Fields are inline and not in one column

With the exception to date fields, normal event registration form fields should be in one column and not next to each other. 


The reason for that? 

With form fields in multiple columns your registrants are more likely to get super confused and misinterpret the fields. 

Mistake #4: Fields are not made required, even though they should be

If you can, try to avoid optional fields in forms. If you do decide to use them, clearly label fields as optional and not as not required.

Not sure which questions to ask?

Mistake #5: Password fields are not protected

Any type of password field should really act as a password field and hide the data entered either through asterisks, e.g. ******* or *$£%!%^ or similar).

Mistake #6: Using single-step instead of multi-step forms

Why is that? 

Splitting the registration form into two or three steps will almost always increase form completion, according to Venture Harbour. The first impression of a multi-step form is less intimidating than a long form with lots of question fields. 

Put crucial questions like payment, password and billing information at the end. 

Sunk cost fallacy is a proven cognitive bias that users are more likely to fill out crucial questions at the end as they’ve already invested time in the progress made filling out previous forms. 

Still with me?


Seeing a progress bar, users are more motivated to complete the form. Even better, display the number of steps until completion. 

Mistake #7: Having too many non-essential questions

It’s a fact that too many non-essential questions on your event registration form decrease conversion rate.

Mistake #8: Not using conditional logic

Instead of overwhelming your registrants with questions that are totally irrelevant, make questions conditional. 

Familiar with “If this, than that”? This is exactly how conditional logic works. Someone selects “Yes, I Want a T-Shirt” and a new dropdown field appears where they can select the t-shirt size

There’s no point asking for size otherwise, right?


Mistake #9: Stacking radio buttons horizontally instead of vertically


Horizontal arrangement of radio buttons can make it challenging for registrants to tell which label the radio button corresponds: the one before the button or the one after. 

Vertical positioning of radio buttons is a little safer here (see example above)

Mistake #10: Not explaining why you’re using sensitive information

People are already concerned over privacy and information security. It is therefore crucial to always make sure you explain why it is needed. You can use a support text below the field to make this more obvious.


Mistake #11: Top left aligned labels are best for readability & completion

Google’s UX researchers found out that aligning labels above fields on the left hand side increases form completion time as quicker to scan. 

This is because it requires fewer ‘visual fixations’, as shown in the graphic below according to UX Movement.


Mistake #12: Not using field labels at all

Form labels tell registrants what the corresponding input fields mean. (No further explanation needed here)

Mistake #13: Making phone number fields required instead of optional

The best practice for using phone numbers in your event registration is one where users don’t even have to think about phone number formatting or country code because it automatically displays it for them.


Auto-formatting the input with geolocation is the best way to present phone number fields. As registrants type in their phone number, the proper format is displayed without any effort from the user. 

This way registrants don’t need to type any parentheses, dashes, slashes, periods, or spaces and the data you collect will be much cleaner.

Mistake #14: Not allowing attendees to navigate back and forth in the registration form

Sometimes, attendees change their mind and need to jump back to the previous step in the registration wizard without losing all their data.  


Mistake #15: Not optimizing your event registration form for speed

Registrants expect forms to be super quick and load fast. 

In fact, for every 100 milliseconds Amazon was able to speed up their website, they saw a 1% increase in revenue. The same goes for event registrations. If you want to increase your conversions, ensure your form is as fast as it can be.

Mistake #16: Registration form doesn’t work in all browsers

This may sound like common sense, but it’s always good to check that your registration form works and looks good on all major browsers and across all devices. 

When in doubt, use a service like BrowserStack.

Mistake #17: Too many questions for each step in a multi-step form

Really goes against the purpose of multi-step forms. 

The goal here is to split up messages logically so that the user has a clear expectation as to what’s happening next. Equally, forcing users to flow through two steps when there’s only one field in each step is unnecessary.

Mistake #18: Placing complex legal messages near buttons

If you need users to agree to disclaimers or terms & conditions, try to combine them into one screen as compared to multiple form fields.


Mistake #19: Not explaining “What’s Next?”

When someone registers through your form they might be wondering how long it will take. You want to make sure you display a progress bar (see mistake #16) but also show a confirmation screen on the last page of the registration. 


Mistake #20: Using “Clear” or “Reset” Buttons

You don’t need to risk registrants accidentally deleting all the information they have previously entered. Most users will be aware that refreshing the page will enable them to start over again. 

Mistake #21: Not Sequencing your questions logically

Although, you want full form control from your event registration provider in terms of moving questions and pages around as you like, you should always sequence questions logically. For example, when entering billing addresses 

Mistake #22: Your forms are just way too long

Enuff said?

Look at these conversion stats from Marketo, the longer the form, the lower the conversion.


Mistake #23: Not using kick-ass event software to build event registration forms

The best way to avoid these UX mistakes is by working with an event registration software provide that can deliver an intuitive, flexible, and easy-to-use system that offers unlimited conditional questions and is built on a modern tech stack.
