What Speed Do You Need? The first fact to be aware of is there are two different types of speeds that matter. The first is download speed. This determines how fast you can download data on a network and it is crucial for streaming. Today, many people use their network to stream videos on services like Netflix. Netflix claims you need a download speed of at least 5Mbps to use HD content on its service at 720p or 1080p. This is the minimum download speed you will need, and if you are using the internet to download any other data at the same time, you will experience a lower level of quality. For 4K quality streaming, you will need at least 25Mbps. 5Mbps will be suitable for the minimum level of network usage such as checking your email or reading blogs. For more usage, you should be aiming for a download speed of 10Mbps. If you want to download high levels of data such as a movie, you need at least 50Mbps for a fast speed. Typically, your upload speed will be lower than your download capability. Most people will be uploading small files such as photos on emails, and for this, you need at least 3Mbps. To upload videos to a sharing network like Youtube you need an upload speed of about 8Mbps.
