Number field in Kiwiform

Learn how to collect strictly numeric responses using the Number field in Kiwiform, a free Typeform alternative built for structured and reliable data collection. This guide explains how to add a Number field, mark it as required, set minimum and maximum limits, and ensure respondents enter valid whole numbers only. Whether you are capturing quantities, ages, counts, order amounts, or other measurable values, the Number field helps you enforce clean, consistent numeric input without formatting errors.

What the Number field does

The Number field is designed specifically for collecting numeric input. Unlike text fields, it only accepts numbers, ensuring your responses remain structured and usable for calculations, filtering, scoring, or logic conditions.

Use the Number field when you need respondents to enter:

  • Age

  • Quantity of items

  • Number of attendees

  • Order units

  • Years of experience

  • Employee count

  • Numeric IDs

  • Ratings expressed as numbers

By restricting the input type, you eliminate text-based errors and maintain consistent data formatting.


Supported input format

The Number field supports:

  • Positive whole numbers only

  • Up to fifteen digits

  • No decimal points

  • No negative numbers

This ensures clean numeric data that works seamlessly with logic, calculations, and integrations.
If you need decimal or currency values, consider using the appropriate field type such as Payment.


Add a Number field to your form

To add a Number field:

  1. Open your form in the builder

  2. Click Add Content

  3. Select Number from the form fields list

  4. Click on the field to open its settings in the Answer panel

Respondents will see a simple numeric input box with a clear placeholder.


Configure Number field settings

Mark as Required
You can make the Number field mandatory.

When enabled:

  • Respondents must enter a number before proceeding

  • Prevents incomplete submissions

  • Useful for mandatory data like age, quantity, or count


Set Minimum Numbers
You can define the lowest allowed value.

For example:

  • Minimum age: 18

  • Minimum order quantity: 1

  • Minimum attendees: 2

When the minimum setting is enabled, respondents cannot enter a number lower than the defined limit.

Set Maximum Numbers
You can define the highest allowed value.

For example:

  • Maximum tickets per person: 5

  • Maximum participants: 100

  • Maximum years of experience: 50

When the maximum setting is enabled, respondents cannot exceed the defined upper limit.


How validation works

If a respondent:

  • Enters text instead of numbers

  • Enters a value below the minimum

  • Enters a value above the maximum

The form will prevent progression until a valid number is entered.

This ensures:

  • Cleaner data collection

  • Reduced manual corrections

  • Accurate reporting and analysis


Common use cases

  • Event registration

  • Surveys and research

  • Order forms

  • Applications

  • Resource allocation


Best practices

  • Be specific in your question

  • Set logical limits

  • Place numeric fields strategically

  • Combine with Logic


Summary

The Number field allows respondents to enter positive whole numbers only. You can mark the field as required and define minimum and maximum limits to control the allowed range. This guide covers setup, validation rules, supported formats, use cases, and best practices to help you collect accurate numeric data inside your forms.
