Do Objects count towards Sanity's Document limit?

No, objects do not count toward Sanity's document limit for a given pricing tier!

Here's the key distinction:

What counts as a "document":

• Only document types count toward your document limit
• Document types are top-level content structures that have type: 'document' in your schema
• They appear in your Studio sidebar and have system fields like _id, _rev, _createdAt, etc.
• Examples: pages, blog posts, products, authors

What doesn't count:

• Object types - These are reusable schema structures used within documents (like address objects, SEO metadata objects, etc.)
• They don't exist independently and can't be created as standalone content
• They're just structured data nested inside documents

Document limits by plan: According to the technical limits documentation:

• Maximum documents: 10 million (customizable for Enterprise customers)
• Free plan: 2,000 unique attributes
• Growth plan: 10,000 unique attributes
• Enterprise plan: Custom attribute limits

What you should be aware of: While objects don't count as documents, they do contribute to your attribute limit. An attribute is any unique path/datatype combination across all documents in your dataset. So if you have complex nested objects with many fields, those fields count as attributes.

For example, an array like [2.718, 3.14, "abc", "def", true] counts as 4 attributes (1 for the array itself, plus 3 for the datatypes: float, string, and boolean).

Bottom line: Use as many object types as you need to structure your content effectively - they won't eat into your document count, only into your attribute limit, which is typically quite generous.
