# How large can my import file be?

Your import file can be up to 100 MB, but other size limits apply.

- Your import file can be up to 100 MB, but each record in your file can’t exceed 400 KB, which is about 4,000 characters. To determine how many fields you can import, use this formula: 4,000 / (average number of characters in an API field name \* 2). For example, if your average field character length is 40, you can import approximately 50 fields.
- You can import up to 90 fields per record.
- Each imported note and each imported description can’t exceed 32 KB. Text longer than 32 KB is truncated.
- Other Bulk API limits apply. If you have missing records or truncated fields due to limits, see [Bulk API Limits](https://developer.salesforce.com/docs/atlas.en-us.api_asynch.meta/api_asynch/asynch_api_concepts_limits.htm) in the Bulk API 2.0 and Bulk API Developer Guide.

Your import is also subject to your org’s storage limit. The size of your import file doesn’t directly correlate to the storage space needed for those records. For example, a 50 MB import file doesn’t create 50 MB of data in Salesforce.

Important Salesforce has replaced the individual import wizards for accounts, contacts, and other objects with the Data Import Wizard. Individual import wizards open in small windows, while the Data Import Wizard opens in a full browser with dataimporter.app at the end of the URL. From Setup, enter Data Import Wizard in the Quick Find box, then select **Data Import Wizard**. The options you see depend on your permissions.
