Internet speed for streaming: How fast internet do you need for Netflix and YouTube?

We live in the age of streaming, where we watch movies, series, and videos online whenever we want. As a result, Netflix, YouTube, Max, Disney+, and other streaming services have become indispensable parts of our lives. But what if your video lags, becomes pixelated, takes forever to load, or doesn't start at all? Let's take a look at what might be causing these issues.

The key to smooth viewing is a fast internet connection

Internet speed is measured in megabits per second (Mbps). For streaming, download speed is crucial, as it determines how quickly data is transferred from the internet to your device—whether it be a computer, phone, tablet, or smart TV.

The higher the download speed, the better the video quality and the smoother the playback you can expect. It also depends on the type of connection you are using. DSL connections typically offer speeds between 5-100 Mbps, and cable connections can reach 10-1000 Mbps.

Mobile 4G LTE networks typically provide 10-50 Mbps, while new 5G networks can achieve real-world speeds of 100-1000 Mbps. Satellite connections offer speeds of 12-100 Mbps but may come with higher latency. The fastest option is fiber optic internet, which commonly offers speeds of 100-1000 Mbps and more.

How to enjoy Netflix or YouTube without lag?

Each streaming service has its own internet speed requirements, which vary depending on the quality of the video being streamed—ranging from standard definition (SD) to ultra-high definition (4K).

Generally, a speed of 3 Mbps is sufficient for standard definition (SD), at least 5 Mbps is recommended for high definition (HD), and a minimum speed of 25 Mbps is needed for ultra-high definition (4K).

More users mean higher demands

The aforementioned speeds apply to streaming on a single device. If you share your internet with family or roommates who also enjoy watching YouTube videos, you will need to consider higher speed requirements.

If you plan to have a family movie night in 4K resolution while your child watches cartoons on a tablet, you'll need a speed of at least 50 Mbps.

Besides download speed, latency, measured in milliseconds (ms), is also critical for streaming. In short, it is the delay between sending a request from your device and its delivery to the server.

High latency results in video lag, delayed sound, slow website response, and an overall poor viewing and gaming experience. For smooth streaming and online gaming, an ideal latency is below 50 ms.

Tips for smooth streaming

If you are struggling with slow internet and streaming feels more like a chore than relaxation, don't despair.

Here are a few tips to at least temporarily improve the situation:

1. Reduce streaming quality – If your video lags, try lowering the streaming quality in your player's settings. While lower video quality isn't ideal, it will help you avoid annoying lag and long load times.
2. Close unused applications – Every running application, whether on your device or other devices in the network, uses up internet bandwidth. Close all applications you're not actively using to free up bandwidth for streaming.
3. Restart your router – Sometimes a simple router restart can help. Turn off your router for a few seconds and then turn it back on.
4. Contact your internet provider – If you consistently struggle with slow internet, contact your provider to discuss options for speeding up your connection.
