Shows the distribution of packet lengths and related information.

Figure 8.6. The “Packet Lengths” window

Information is broken down by packet length ranges as shown above.

Packet Lengths : The range of packet lengths.

Ranges can be configured in the “Statistics → Stats Tree” section of the [Preferences Dialog](https://www.wireshark.org/docs/wsug_html_chunked/ChCustPreferencesSection.html).

Count : The number of packets that fall into this range.

Average : The arithmetic mean of the packet lengths in this range.

Min Val, Max Val : The minimum and maximum lengths in this range.

Rate (ms) : The average packets per millisecond for the packets in this range.

Percent : The percentage of packets in this range, by count.

Burst Rate : Packet bursts are detected by counting the number of packets in a given time interval and comparing that count to the intervals across a window of time. Statistics for the interval with the maximum number of packets are shown. By default, bursts are detected across 5 millisecond intervals and intervals are compared across 100 millisecond windows.

These calculations can be adjusted in the “Statistics” section of the [Preferences Dialog](https://www.wireshark.org/docs/wsug_html_chunked/ChCustPreferencesSection.html).

Burst Start : The start time, in seconds from the beginning of the capture, for the interval with the maximum number of packets.

You can show statistics for a portion of the capture by entering a display filter into the Display filter entry and pressing Apply.
