Numeric stepper guidelines

Numeric steppers allow users to click through numbers with a small value.

States

Numeric steppers change their state or appearance so that users know what to do. These little visual cues nudge the user in the right direction.

Normal

This is the default state for most numeric steppers, and it means that the user can change the number using the buttons.

Disabled

This state means that the numeric stepper is disabled and that you can’t change its value. It may be disabled due to business rules or because the user needs to select something else first.

Best practices

There are a few best practices when it comes to numeric steppers. Overall, you want to make the already laborious task of filling out forms as easy and intuitive as possible.

Always have a label

Your numeric indicator should always be paired with a label so that users know how to complete the field.

Only use numeric steppers for small values

Numeric steppers work best for numbers between 0 and ~10. More than that, and it can get very laborious for the user to click through, and it’s advised to use a different input.

Always set a default

Numeric steppers should always have a default. The default will usually be ‘1’. Sometimes, you will have steppers defaulted to ‘0’. For example, when booking a hotel room, it may set the default number of adults as ‘1’ and the default number of children as ‘0’.

Use it if the average user will not deviate from the default

Steppers can be painful to use if the user isn’t looking for an option similar in value to the default. If you expect the user to deviate substantially from the default, use a different input.

Consider having numeric steppers in a column

When reading out items in an online shopping cart, consider having the numeric steppers in a column. This makes it easier for the user to skim read and see where there are more or fewer items than they need.

When to use a numeric stepper

Numeric steppers are perfect in some instances but not in all.

When you should use a numeric stepper:

• If the values are small.
• If you expect that users will seldomly deviate from the default option.

Numeric steppers vs. numeric input fields

A numeric input field is like a regular text field, except you can only input numbers into it. In some instances, this might be better than using a numeric stepper.

When you should use a numeric input field:

• If it’s likely that the user will deviate from the default amount.
• If the user does not need to know what the limits are.

Numeric steppers vs. sliders

Sliders, like numeric steppers, are a numeric single selector. Sliders are better than numeric steppers in some cases.

When you should use a slider:

• If there is a wide range of numeric options.
• If the user needs to be able to see the minimum and the maximum numbers.
• If the numeric values aren’t small.

Variations

Using more specific input styles makes it more apparent to the user how they’re expected to complete the form.

DIY Symbols

Make your own custom numeric stepper Symbols in Balsamiq using other pre-made controls.

Stepper with input: For larger values, consider having a stepper with an input so that the user can choose to type or click to their desired number.
