| The maximum size of a message or batch for a newly-created topic.

The default is *20 MiB* for BYOC and Dedicated clusters, and *8 MiB* for Serverless clusters. You can increase this value up to *32 MiB* for BYOC and Dedicated clusters, and *20 MiB* for Serverless clusters, with the `message.max.bytes` topic property.

| *Segment size*
| The maximum size of a log segment. When a segment reaches this size, Redpanda closes it and starts a new one.

The default is *128 MiB*, set at the cluster level. This differs from self-managed Redpanda, where the default is 1 GiB. You can override the segment size for a topic with the `segment.bytes` property, within limits that depend on your cluster tier.
