CMS: Understanding Collection Storage Limits and Quotas

Lord Of The Wix · Oct 25, 2026

The Wix CMS (Content Management System) lets you store and manage content in collections, giving you the flexibility to create dynamic, data-driven sites. Understanding your storage limits ensures you can plan your site's content effectively and avoid unexpected interruptions.


Every site has different data needs, and Wix provides storage limits based on your Premium or Studio plan to ensure optimal performance. These limits include the number of collection items you can store, the size of each item, and your total database storage capacity.


Important:


Business Elite and Elite plans now support up to 10 million collection items and 100 GB of total database storage, significantly expanding what you can build with the CMS.


Store more content with expanded item limits


Wix limits the total number of items you can store across all your CMS collections. The number of items you can store depends on your Premium or Studio plan, allowing you to scale your site as your content grows.


Collection item limits by plan:



Once you reach your plan's item limit, you won't be able to add more data to your collections. To continue adding items, delete existing items or upgrade your plan to receive more storage.


What counts toward your item limit:



What doesn't count toward your item limit:



Keep individual items within size limits


Each individual item in your collection can store up to 512 KB of data across all its fields combined. This limit applies to text, numbers, URLs, tags, and other non-media field types.


For example, if you have a recipe collection with fields for a recipe name, description, ingredients list, cooking instructions, and tags, the total size of all those fields together for one item cannot exceed 512 KB.


Important:


Media files stored in image, video, audio, document, and media gallery field types are not counted toward the 512 KB per-item limit. These files are stored in your Media Manager and have separate storage limits.


Tips:



Manage your total database storage


In addition to item limits, Wix also caps the total database storage your site can use. This cap applies to the combined size of all items across all your CMS collections and helps ensure optimal performance for all Wix sites.


Total database storage by plan:



Once you reach your total database storage cap, you won't be able to add more data to your collections, even if you haven't reached your item limit. To free up space, delete items you no longer need or upgrade your plan.


Note:


This database storage cap is separate from your site's media storage (used for images, videos, and other files uploaded to your Media Manager).


Important:


We're working on releasing the Data storage option, which is not yet available in all Wix accounts. If you don't see it, enable coding in your editor, go to Monitoring in your site's dashboard and click the CMS collection storage tab.


To check your CMS storage usage:


  1. Go to CMS in your site's dashboard.

  2. Click More Actions and click Data storage.

  3. View your collections usage:

    • Collections: The number of collections you created.

    • Collection items: The total number of items across your collections.

    • Storage used: The total database storage your collections use.

    • Collection table: The number of items and the storage used by each collection.

Tips:



How app collections affect your storage


When you install apps on your site, some apps create collections to store their data using the Wix Data API. How these collections count toward your storage quota depends on the type of app.


Wix app collections:



Public app collections:



Private app collections:



Tip:


You can identify app collections by the @ symbol in their name. Public app collections (installed from the App Market) don't count toward your quota, while private app collections (apps you develop yourself) do count.

Optimize your data storage


If you're approaching your storage limits, there are several ways to reduce the amount of storage your site uses and stay within your quota.


Delete data you don't need

Make sure your collections only contain data that you need for your site. Review your collections regularly and remove items that are no longer relevant. Keeping only the data you need helps you stay within your limits.


Delete sandbox items

Sandbox collections have their own separate storage quota, equal to your live data quota. For example, if your plan allows 4,000 items, you can store up to 4,000 items in your sandbox collections in addition to your 4,000 live items.

Sandbox is used to test your site with Velo code in your editor preview. Sandbox data is only used in your editor and does not appear on your live site.

When you disable sandbox for a collection, sandbox items are stored for 7 days before being permanently deleted. To free up your sandbox quota sooner, manually delete sandbox items from your collection.


Use external databases

The collection storage quota doesn't apply to external databases. If none of the other options work for you, store your data in an external database and integrate it with your site. You can still access this data using Velo and the Wix Data API.


Upgrade your plan

Upgrade your plan to receive more resources and significantly higher storage limits.


FAQs


Click below for answers to common questions about collection storage limits.


What happens if I exceed my storage quota?

If you reach your collection item limit or total database storage cap, you won't be able to add new items to your collections. Delete existing items to free up space, or upgrade your plan to increase your limits.


Do media files count toward my database storage cap?

No. Media files stored in image, video, audio, document, and media gallery field types are not counted toward your 512 KB per-item limit or your total database storage cap. These files have separate storage limits.


What happens if I downgrade my plan?

If you downgrade to a lower-tier plan, your storage quota changes to match the new plan. If your site has more data than the new quota allows, none of your data is deleted. However, you won't be able to add new data until you delete enough existing data to fall below the quota.


Can I see how much storage I'm currently using?

Yes. You can check your storage usage from More Actions in the CMS.

You can also see your current item count under Your Collections in the CMS (e.g. "You have 331/500000 items").


What are the storage limits for free Wix sites?

Free Wix sites have different collection item limits depending on whether your account is part of the Wix Studio platform:

Learn more about CMS limits on free sites.


How do Partners and Studio users' free-tier limits differ?

Partners and Studio users automatically have access to the Wix Studio platform, which provides higher CMS limits on free sites. Free sites in Wix Studio accounts have a collection item limit of 10,000 items, compared to 1,000 items for non-Studio free accounts.

If you're a Wix Partner and choose to leave Wix Studio, your free site CMS quota reverts to 1,000 items. Keep in mind that leaving Wix Studio also opts you out of the Partner Program entirely.

Can I increase my storage limits without upgrading?

No. Storage limits are determined by your Premium or Studio plan. To increase your limits, you need to upgrade to a higher-tier plan.


Do items in Wix Forms collections count toward my storage?

No. Submissions in Wix Forms collections do not count toward your CMS collection item limit or database storage cap because Wix Forms collections are Wix app collections. Learn more about Wix Form collections.
