Start With the Right Test

Different internet problems need different measurements. These are the most useful starting points.

Broadband Speed Test

Check download, upload, ping, jitter, and packet loss in one browser test.

Advanced Speed Test

Use the full diagnostic test for server choice, charts, and deeper metrics.

Wi-Fi Speed Test

Find out whether your wireless network is the bottleneck.

Loaded Latency Test

See whether downloads make ping spike during games, calls, or remote work.

Website Audit

Check page speed, SEO tags, internal links, crawlability, schema, and security headers.

What we measure

A complete picture of your connection quality - Not just one number.

Download

How fast your connection receives data. Affects streaming quality, page load times, and video call clarity.

Broadband speed test →

Upload

How fast your connection sends data. Critical for video calls, cloud backups, and live streaming.

What is a good upload? →

Ping

Round-trip response time to the test server. Lower is better - Directly determines gaming and call responsiveness.

Ping test →

Jitter

Variation in ping between measurements. High jitter causes choppy audio and video even when average speed is high.

What is jitter? →

Packet Loss

Percentage of data packets that fail to reach their destination. Even 0.5% degrades VoIP and online gaming severely.

Packet loss test →

Loaded Latency

Ping measured while the connection is under full load - Simulates how your network behaves in real-world conditions.

Common Questions

How accurate is Speedtest.now?

We use multi-threaded download and upload tests to saturate your connection, giving a realistic measurement of your bandwidth. Results may vary based on server load, your device, and Wi-Fi interference. For best accuracy, use a wired Ethernet connection and close other applications. See accuracy tips →

Does testing use data from my plan?

Yes. A standard test transfers approximately 40–200 MB depending on your connection speed. If you're on a metered connection, be aware of this before running multiple tests.

Why is my speed lower than my plan?

Many factors affect measured speed: Wi-Fi signal quality, router firmware, ISP congestion, your device's hardware, and VPN usage. Read our guide on slow internet →

Is my data private?

Your IP is never shown publicly. We store a masked version for rankings and only use your results for aggregated statistics. Read our full privacy policy →

Privacy First

Your IP address is never displayed publicly. We store only a masked, hashed version for aggregate analytics. You choose whether to save results to your account.

Multi-Stream Testing

Unlike single-connection tests, we run up to 4 parallel streams to fully saturate your connection - The same technique used by professional network engineers to measure true bandwidth.

Global Server Network

Test against servers in multiple continents. Our algorithm selects the closest server to minimise propagation delay, giving you the most representative result for your location.

Transparent Methodology

Every measurement - From how we calculate ping to how we handle packet loss - Is documented. We use median throughput, not peaks, so you get a realistic number, not a marketing figure.

What Affects Internet Speed?

Speed test results are influenced by several layers of your network. Understanding each one helps you diagnose problems faster.

Wi-Fi signal

Distance from your router, walls, and interference from nearby devices reduce wireless throughput. Use Ethernet for the most accurate baseline.

ISP congestion

ISPs share bandwidth between subscribers. During peak hours (evenings), speeds can drop 20–60%. Test at off-peak times to isolate this.

Router hardware

Routers older than 5 years often cap at 100–300 Mbps regardless of your plan. The router is a frequent bottleneck on gigabit connections.

VPN overhead

VPN encryption adds 10–40% latency and reduces throughput. Disable your VPN before testing to measure your true ISP-provided speed.

Device CPU & NIC

Older devices with slower CPUs or network cards can't process data fast enough to saturate a modern connection - The device itself becomes the cap.

Server distance

Every 100 km of fibre adds roughly 0.5 ms of latency. We auto-select the nearest server, but you can change it manually to test different routes.

Connected devices

Every device sharing your connection competes for bandwidth. 10 devices on a 100 Mbps plan leaves ~10 Mbps each under simultaneous load.

Modem age & type

DOCSIS 2.0 modems cap at ~30 Mbps. Ensure your modem tier matches your plan - Your ISP can confirm the right DOCSIS version for your speed tier.

DNS resolution

Every site visit starts with a DNS lookup. ISP-default DNS can add 50–200 ms per request. Switching to Cloudflare (1.1.1.1) often reduces this noticeably.

ISP peering & routing

Traffic between your ISP and major content providers can bottleneck even on fast local connections. This causes slow speeds to specific services, not all sites.
