Speed Test for Zoom

Zoom is real time, so jitter and packet loss matter as much as raw bandwidth. Choppy audio, frozen video, and dropped calls destroy your credibility on sales calls, interviews, and exec meetings. A passing speed test the night before will save you from a 9am disaster the next morning.

// How to test for Zoom

  1. 01
    Close Zoom and competing apps
    Quit Zoom, Slack huddles, browser tabs streaming video, and any cloud sync (Dropbox, OneDrive, iCloud Photos) so the test reflects real headroom, not contested bandwidth.
  2. 02
    Run the test on the device you actually use for Zoom
    If you take calls on a laptop over Wi-Fi, test on that exact laptop in the room you take calls in. Wi-Fi performance varies by 10x across rooms in the same house.
  3. 03
    Check download, upload, ping, and jitter
    You need 3.8 Mbps down and 3.8 Mbps up sustained for HD group video. Ping should be under 150ms to a regional server, jitter under 30ms.
  4. 04
    Re run with a partner on a second device
    If your household has multiple Zoom users, run two tests at once on different devices. Most home routers cannot deliver HD video to two simultaneous calls without dropping frames.

// Tips for Zoom

  • Use a wired Ethernet cable for important calls. Wi-Fi adds 5 to 25ms of jitter even on a strong signal, and Zoom is unforgiving of jitter spikes.
  • Close every app that uses upstream bandwidth before the call: cloud backups, Dropbox sync, AirDrop, and any other video tool.
  • If you must use Wi-Fi, sit in the same room as the router or upgrade to a mesh system. One drywall layer can drop your usable speed by half.
  • Run a bufferbloat test under load. If your router has high bufferbloat, your audio will glitch the moment anyone in the house hits a download.
  • Test 30 minutes before any high stakes call. ISP congestion peaks between 7pm and 11pm and can briefly tank your numbers.
  • Plug your laptop into power. Some laptops throttle Wi-Fi radios on battery to save power, hurting call quality.
  • If your upload is below 3.8 Mbps and you are on cable or DSL, ask your ISP to upgrade you to a symmetric or higher upload tier. Many ISPs now offer this for an extra few dollars per month.

// Frequently asked questions

?>What internet speed do I need for Zoom?
Zoom recommends 3.8 Mbps down and 3.8 Mbps up for HD group video, 1.8 Mbps down and 1.8 Mbps up for HD 1 on 1, and as low as 600 Kbps for screen sharing only. Ping should stay under 150ms to your nearest Zoom region, and jitter should stay under 30ms. If you fall under those, expect choppy audio, frozen video tiles, or full call drops.
?>Why does Zoom freeze even though my speed test is fast?
Speed is only one factor. Zoom is real time, so it is killed by jitter, packet loss, and bufferbloat, none of which show up in a basic Mbps number. Run our jitter test and bufferbloat test to confirm the connection is stable under load. The most common culprit is a router with no SQM whose latency spikes the second anyone else streams or uploads.
?>Is Wi-Fi good enough for Zoom?
It can be, but Ethernet is always more reliable. Wi-Fi adds jitter and is sensitive to interference from microwaves, neighboring access points, and the number of devices on the band. For high stakes calls (interviews, board meetings, sales demos), use a wired connection. For day to day standups, modern Wi-Fi 6 or mesh in the same room as the router is fine.
?>How do I improve Zoom call quality?
In order of impact: switch to Ethernet, sit closer to the router or add a mesh node, close every app using upstream bandwidth (cloud sync, Dropbox, AirDrop), enable QoS or SQM on your router to fix bufferbloat, and prioritize the 5 GHz band over 2.4 GHz if you must use Wi-Fi. Plugging your laptop into power also helps on some models.
?>Should I run a speed test before every Zoom call?
Before important calls, yes. ISP performance varies by time of day and Zoom call quality varies based on which other apps and household members are competing for bandwidth. A 60 second test takes less time than the awkward apology after your video freezes during a pitch.
