What Is Ping? Why Latency Matters for Gaming, Calls & Browsing

When you run a broadband speed test, you get three numbers: download speed, upload speed, and ping. Most people focus on the first two and completely ignore ping — but for gaming, video calls, and anything interactive, ping is arguably the most important of the three.

What Is Ping?

Ping measures the time it takes for a small packet of data to travel from your device to a server and back again. Think of it like shouting across a valley and timing how long it takes to hear the echo. The faster the echo returns, the better your connection's responsiveness.

The term comes from sonar technology — submarine operators use "ping" to describe the sound pulse sent out to locate objects. In networking it's exactly the same concept: send a signal, measure the round-trip time.

How Is Ping Measured?

Ping is measured in milliseconds (ms). One millisecond equals one thousandth of a second. The lower the number, the faster your connection responds. You'll also sometimes see the related term latency used interchangeably — they refer to the same thing.

A related metric is jitter — the variation in ping over time. A connection with an average ping of 20ms but occasional spikes to 80ms has high jitter. Jitter causes stuttering in video calls and rubber-banding in games, and is often more disruptive than consistently high ping.

What Is a Good Ping?

Why Ping Matters

Gaming

In online games, every action you take — a shot fired, a car steered, a character moved — sends a signal to the game server which then tells all other players. If your ping is 200ms, there's a 0.2 second delay between pressing the trigger and the shot registering. In fast-paced games like Call of Duty or Fortnite, 0.2 seconds is an eternity. Your opponent fires at where you were, not where you are.

Video Calls

Video calls on Zoom, Teams, and Google Meet are surprisingly tolerant of slow download speeds but very sensitive to high ping. A ping over 150ms starts to cause audible delays and the awkward "after you... no, after you" pauses in conversation.

General Browsing

High ping makes web pages feel sluggish to begin loading, even if they load quickly once started. Every link click, form submission, and page load requires a round trip to a server — high ping adds a noticeable delay before anything starts happening.

What Causes High Ping?

• Physical distance. Data travels at the speed of light, but distance still adds up. A server in the USA will always have higher ping than one in London.
• Network congestion. During peak hours (7–10pm), busy network infrastructure increases latency. This is why ping often spikes in evenings.
• Wi-Fi interference. Wireless connections add latency compared to wired Ethernet. Every hop through a wireless link adds a few milliseconds.
• Old or overloaded routers. A cheap router managing dozens of devices can add significant latency as it struggles to process packets.
• A VPN. Routing your connection through a VPN server adds an extra network hop, increasing ping — sometimes dramatically if the VPN server is in another country.

How to Reduce Your Ping

• Switch to Ethernet. Plugging directly into your router typically cuts latency by 5–20ms and eliminates Wi-Fi jitter entirely.
• Upgrade to Full Fibre (FTTP). Full fibre connections have inherently lower and more consistent latency than FTTC or ADSL.
• Connect to UK-based game/app servers. Most services auto-select the closest server, but check your settings if you're consistently experiencing high ping.
• Disable background downloads. Windows updates, cloud backups, and game downloads during play cause jitter even on fast connections.
• Restart your router. Over time, routers can develop memory issues that increase latency. A weekly restart helps keep things running smoothly.
