# Size Limits

Sentry imposes size limits on events, attachments, requests, and various event fields.

## [Behavior](https://docs.sentry.io/concepts/data-management/size-limits.md#behavior)

The following describes how Sentry treats size limits:

* Events, attachments, and requests exceeding payload size limits are immediately dropped with a `413 Payload Too Large` error.
* Sentry allows compressed content encoding, and applies separate limits before and after decompression.
* Events that exceed 200KB compressed or 1MB decompressed will be rejected.
* Minidump uploads that exceed 40MB compressed or 200MB decompressed (for all files combined) will also be rejected.
* Event fields exceeding the individual size limits are trimmed and truncated afterwards.
* The number of events rejected due to size limits is counted towards the *Dropped* category in [usage stats](https://docs.sentry.io/product/stats.md#usage-stats).

## [Recommendations](https://docs.sentry.io/concepts/data-management/size-limits.md#recommendations)

To avoid using up your attachments quota — which is based on size and not number of instances of attachments data sent — or having the event dropped entirely, consider limiting the size of values passed into Sentry's APIs. For example, if your application attaches application state or request bodies to Sentry events, truncate them first.
