 ## Partitioned entities limitations
 Currently Service Bus imposes the following limitations on partitioned queues and topics:
 
-- For partitioned premium namespaces, the message size is limited to 1 MB when the messages are sent individually, and the batch size is limited to 1 MB when the messages are sent in a batch.
+- For partitioned premium namespaces, the message size is limited to 1 MB when the messages are sent individually, and the batch size is limited to 1 MB when the messages are sent in a batch. If [Large message support](/azure/service-bus-messaging/service-bus-premium-messaging) is enabled the size limit can be up to 100MB.

 - Partitioned queues and topics don't support sending messages that belong to different sessions in a single transaction.
 - Service Bus currently allows up to 100 partitioned queues or topics per namespace for the Basic and Standard SKU. Each partitioned queue or topic counts towards the quota of 10,000 entities per namespace.
