Data limits and guardrails
To improve performance, reliability, and scalability in Jira Cloud family of apps, new limits and guardrails are being introduced for custom fields, work types, work items, and spaces. These changes help you manage data more effectively and prevent performance issues as your site grows.
This page explains what’s changing, why, and how you can stay within the new boundaries.
This page is for company-managed spaces
To check whether your space is team-managed or company-managed, select More actions (•••) next to the space name in either the header or the sidebar. At the bottom of the menu that opens, your space details will be shown.
More about the difference between company-managed and team-managed spaces.
Team-managed spaces have a current limit of 50 custom fields per space.
What’s changing
Guardrails are recommended data thresholds. If you exceed them, your site’s performance may be affected. These are best practices, not mandatory.
Limits are data thresholds that can’t be exceeded.
New limits starting February 2026
Starting February 2026, the Jira Cloud family of apps will enforce new hard limits on certain data types to prevent performance issues as your site grows.
The limits are:
Fields: Maximum 700 fields per space
Work types: Maximum 150 work types per space
Guardrails and best practices
We recommend following these guardrails for easier data management and configuration.
The guardrails are:
Work items: 18,000,000 work items per site
Spaces: 8,400 spaces per site
How to meet the limits
You must have the following to do the things described in this section.
Role: Site admin
The best way to reduce your footprint is to reuse existing global fields and delete outdated fields, work types, work items and spaces, helping to optimize your site for expansion and usability. Read about ways you can optimize your field configuration specifically
Start by understanding your site’s current usage.
The Field configuration schemes will show the number of fields included in your site. The Work type schemes will show the number of work types on your site. They’ll both let you know if you're approaching the limit, and offer ways to clean up unused data across spaces. The same applies to work types.
To view and manage your site’s usage:
From the global navigation, go to Settings (), then Work items.
From the sidebar, navigate to either Work type schemes or Field configuration schemes.
Review your fields or work types. Select Optimize scheme (even if you’re under the limit).
To remove unused fields or work types, select Review actions in the first section.
To create a new scheme with only current and used fields or work types, select a space in Create a scheme variant, then Review actions.
Select Redefine configuration scheme to group spaces that use similar fields or work types and create a new scheme.
Starting in February 2026, if your space exceeds the custom field or work type limit, you’ll be prevented from associating additional fields or work types to your scheme until you reduce your data.
We won’t delete any existing data as a result of these changes.
