Is your internet fast or slow? Not sure how to tell if you’ve got a good internet speed? Here’s how to find out if you have the right speed for your needs.

At Allconnect, we work to present quality information with editorial integrity. While this post may contain offers from our partners, our opinions are our own. Here’s how we make money.

Next to price, internet speed is one of the main decision drivers when shopping for internet or evaluating your current internet service. But, unlike price – where you can easily look at the monthly cost and say “that fits my budget” or “that’s a new car payment” – internet speeds can be a bit more tricky to gauge.

Is 100 Mbps “fast” internet? Is 10 Mbps “slow”? What internet speeds do I get? These are all questions many of us ask, so we’ve created this simple guide to explain them.

Let’s look at how internet speed is measured, what is considered fast internet, what may be slow internet and other factors to help you answer the question: What is a good internet speed?

How is internet speed measured?

Internet speed is determined by how much data the connection can download (download speeds) or upload (upload speeds) per second.

In both cases, the speed is shown as bits per second (bps). Since an internet connection transfers thousands of bits per second, we use the prefixes k, M and G to show how many thousands of bits we’re talking about. If you’re familiar with the metric system, you know “k” = 1,000, “M” = 1,000k (1,000,000) and “G” = 1,000M (1,000,000,000).

When researching internet speeds, you’ll likely see Mbps more than kbps or Gbps. That’s because Mbps speeds are more suited to what we use the internet for.

When are download speeds important?

For most households, having fast download speeds is most important. That’s what we use for common activities such as streaming TV, downloading music and browsing social media.

When are upload speeds important?

Upload speeds come into play with things like video conferencing and uploading large files to a server or cloud. Check out this blog for more information about download vs. upload internet speeds.

Speeds that fall into the kbps range are generally what we’d call “slow” internet and Gbps speeds, which are less prevalent but becoming more common, are in the ultra-fast range.

Think of “broadband” as the national internet speed limit

Per the Federal Communications Commission (FCC), a broadband internet connection has a minimum download speed of 25 Mbps and a minimum upload speed of 3 Mbps. This gives us a baseline for determining fast and slow internet speeds.

Speeds much faster than a standard broadband connection are generally considered “fast” internet. While all speeds below that threshold aren’t necessarily slow, they are too slow to be considered broadband internet.

Keep in mind there are many things that can affect actual internet speeds and performance. Adding connected devices and using the internet for demanding tasks such as streaming in 4K or downloading an HD movie can hinder performance and make even “fast” speeds seem slow.

What is a good internet speed?

A good internet speed is at or above 25 Mbps. These speeds will support most online activity, such as HD streaming, online gaming, web browsing and downloading music.

Fast internet speeds, those in the 100+ Mbps range, are often better, especially if you want your internet plan to support multiple devices and users at once.

What is considered fast internet?

Internet download speeds of 100 Mbps or higher are often considered fast internet because they can handle multiple online activities for multiple users at once without major interruptions in service. If you need a little help determining the best internet speeds for your needs, we’ve got you covered.

Common fast internet speed tiers include:

  • 100 Mbps
  • 200 Mbps
  • 250 Mbps
  • 300 Mbps
  • 400 Mbps
  • 500 Mbps
  • 1,000 Mbps
  • 2,000 Mbps

Cable internet and fiber-optic internet services are your best bets for fast internet speeds. Fiber-optic internet is also a great choice for speed consistency, as it is less vulnerable than cable to slower speeds during peak usage times.

Popular cable or fiber-optic internet providers include AT&T, CenturyLink, Cox, Frontier FiOS, Optimum, Spectrum, Suddenlink, Verizon Fios, Xfinity and Windstream. Many of these providers offer speeds up to 940-1,000 Mbps in select areas, but Xfinity is currently the only provider with speeds up to 2,000 Mbps.

What are fast internet upload speeds?

Upload speeds of 10 Mbps or higher are generally considered fast internet speeds for upload because they can easily handle the common activities of the average user. For example, Skype recommends upload speeds of 1.2 Mbps or higher for HD video calling. Uploading a large file, like 700 MB file document, should take less than 10 minutes with a 10 Mbps upload connection.

What is considered slow internet?

Download speeds less than 25 Mbps are too slow to be considered broadband. With these speeds, users may experience buffering when streaming video, difficulty connecting multiple devices and other internet connectivity issues.

When connecting multiple devices, streaming in HD or using a Wi-Fi connection, speed tiers that could be considered slow include:

  • Anything less than 1 Mbps
  • 3 Mbps
  • 5 Mbps
  • 10 Mbps
  • 15 Mbps
  • 18 Mbps

The FCC does recommend speeds less than 25 Mbps for many online activities, including streaming SD and HD video, gaming online and downloading music. However, these are minimum speed recommendations and do not account for connecting multiple devices or other factors that may slow your internet speeds.

What types of internet connections are more likely to be slower?

Think your internet is slow? Take a speed test

An internet speed test will give you a good idea of whether or not you have the necessary speeds for your household. For best results, take the speed test with a wired connection. If you get speeds below 25 Mbps, you may have a slow internet connection that can’t keep up with all your online activity.

Your speed test results:

Download Speeds

888 Mbps

Upload Speeds

88 Mbps

Pro Tip: For best results, use an Ethernet cord to connect your router or modem directly to your device before you run the test.


If you have slow internet, there may be other internet providers in your area that offer faster speeds. Or, your current internet provider may offer plans with higher speeds. Shop around to find a faster internet speed if your current provider and plan doesn’t offer the speeds you need.

How much of a difference does a good internet speed make?

Small speed increments, such as 15 to 25 Mbps, likely won’t result in a noticeable difference in performance, but larger jumps, say 10 to 100 Mbps, can give you a totally different experience.

To give you an idea of how much speed can play a role in downloading and uploading, we’ve listed the estimated time it would take to download a two-hour HD movie and upload a 10-minute video with various speeds below.

How long does it take to download a movie?

File sizes for things like music, movies and pictures vary, but a movie can range from 1 to 7 GBs depending on the length and picture quality. Here’s how long it would take in hours:minutes:seconds to download a 4 GB file at various speeds.

How long does it take to upload a short video?

Video files vary in size, but let’s say you have a 500 MB clip, which could amount to 10 minutes or more in standard definition. Here’s an estimate of how long it would take to upload it with various upload speeds.

Keep in mind, upload speeds from internet providers are often significantly lower than download speeds. Some fiber-optic providers, however, do offer upload speeds comparable to their advertised download speeds.

These download and upload times are estimates, based on a constant speed. As mentioned above, there are many factors, such as the number of connected devices and types of internet activities performed, that can affect internet speeds and the time it takes to perform a given task.
