How Long Does It Take to Download a 100 GB Game?
Learn how long it takes to download a 100 GB game at different internet speeds, plus factors that affect download time and ways to speed it up.
Downloading a 100 GB game can take anywhere from a few hours to more than a day, depending on your internet speed. A fast 1 Gbps connection can download it in around 15 minutes under ideal conditions, while a 100 Mbps connection may take about 2 hours and 20 minutes.
However, actual download times are often longer because of server limits, network congestion, and other devices using your internet connection.
Different Internet Speeds and Download Time for a 100 GB Game
Your internet download speed is the main factor that determines how long a 100 GB game takes to download. A faster connection transfers more data per second, reducing the total waiting time.
Here are the estimated download times for a 100 GB game at different internet speeds:
10 Mbps: Around 22 hours and 13 minutes
20 Mbps: Around 11 hours and 7 minutes
25 Mbps: Around 8 hours and 53 minutes
50 Mbps: Around 4 hours and 27 minutes
100 Mbps: Around 2 hours and 13 minutes
200 Mbps: Around 1 hour and 7 minutes
300 Mbps: Around 44 minutes
500 Mbps: Around 27 minutes
1 Gbps (1,000 Mbps): Around 13 minutes and 20 seconds
2 Gbps (2,000 Mbps): Around 6 minutes and 40 seconds
These estimates assume a constant download speed and use 100 GB as 100 billion bytes. Your actual download time may be longer because internet speeds fluctuate, and game servers may not deliver data at your connection's full speed.
Why Does Downloading a 100 GB Game Take Longer Than Expected?
Even if you have a fast internet connection, a 100 GB game may take longer to download than the estimates above suggest. Several factors can affect the final download time.
1. Your Actual Download Speed
The speed advertised by your internet service provider is not always the speed you receive when downloading a game. For example, your plan may offer 100 Mbps, but your download speed could drop to 70 Mbps during busy hours. It’s a confusing issue, and you can learn about it better by reading our guide about “Why Download Speed Looks Lower Than Your Internet Plan”.
Now, at 70 Mbps, downloading 100 GB takes around 3 hours and 10 minutes under ideal conditions. This is about an hour longer than the estimated time at 100 Mbps.
You can check your current download speed using an internet speed test. Run the test while connected to the same network you use for gaming to get a more useful estimate.
2. Game Server Speed
Your internet connection is only one part of the download process. The platform hosting the game must also send the data to your device.
Steam, Epic Games Store, PlayStation, Xbox, and other gaming platforms may deliver different download speeds depending on server load and your location. If a game launches and thousands of players try to download it at once, the servers may become congested.
Even with a fast internet plan, you may not reach its maximum speed during these periods.
3. Wi-Fi and Ethernet Connection
Your connection type can also affect download speed. Wi-Fi may become slower because of distance from the router, walls, interference, or other connected devices.
A wired Ethernet connection usually provides a more stable connection, especially when downloading large games on a PC or console. If you use Wi-Fi, try moving closer to the router or connecting your device to the 5 GHz band if it supports it.
4. Other Devices Using Your Internet
If other people are streaming videos, downloading files, or playing online games, they may use part of your available bandwidth.
For example, if your connection provides 100 Mbps and another device uses 30 Mbps, your game download may have roughly 70 Mbps available if both activities run at the same time. This can increase the time needed to download the full game.
Pause unnecessary downloads and updates on other devices to give your game more available bandwidth.
5. Your Storage Drive Speed
Your storage drive can affect how quickly a game downloads and installs. An SSD can write incoming game files faster than a traditional hard drive, but your internet connection and the game server still determine how quickly the data reaches your device.
For example, SSD download speed over a fast internet connection depends on both the available network bandwidth and the drive's ability to handle incoming data. If the drive is busy or nearly full, saving and processing game files may take longer.
Some games also need extra time to unpack or verify files after downloading. This adds to the total waiting time, even after the internet transfer is complete.
How to Calculate the Download Time for a 100 GB Game?
You can estimate the download time for any internet speed using a simple formula.
Download time in seconds = File size in bits ÷ Download speed in bits per second
A byte contains 8 bits, so a 100 GB game contains approximately 800 gigabits of data.
For example, if your internet speed is 100 Mbps:
Convert the file size to megabits: 100 GB × 8,000 = 800,000 megabits.
Divide the file size by your download speed: 800,000 ÷ 100 = 8,000 seconds.
Convert seconds into minutes: 8,000 ÷ 60 = approximately 133 minutes.
At a constant 100 Mbps, downloading a 100 GB game takes around 2 hours and 13 minutes. Internet providers use Mbps, while game launchers often show MB/s. Since 1 MB/s equals 8 Mbps, a 100 Mbps connection can reach 12.5 MB/s under ideal conditions.
If you don’t want to get into this manual calculation, you can use a Download Time Calculator. In this tool, you can enter details like the file size and your internet speed to get the estimated download time.
How to Download a 100 GB Game Faster
If your game is taking too long to download, a few simple changes may help.
Use Ethernet: Connect your PC or console directly to your router to reduce wireless interference and improve connection stability.
Pause other downloads: Stop unnecessary downloads, updates, and large file transfers on your network.
Close bandwidth-heavy apps: Pause cloud backups, file-sharing programs, and video streams that use your internet connection.
Check the game launcher: Look for download limits in Steam or other launchers and remove any limit that is unnecessarily restricting speed.
Choose a nearby download region: If your gaming platform offers server or download-region settings, try a nearby region with better performance.
Download outside busy hours: If your connection slows down in the evening, try downloading the game during quieter hours.
Check your storage space: Make sure your drive has enough free space for the download and installation. Some games require additional space to unpack or update files.
These steps cannot make your connection faster than its actual capacity, but they can help you get closer to the speed your internet plan supports.
Final Words
Downloading a 100 GB game can take anywhere from a few minutes to several hours, depending on your internet speed and other factors. At 100 Mbps, you can expect around 2 hours and 13 minutes under ideal conditions, while slower connections may take much longer.
To reduce waiting time, use a stable connection, pause other downloads, and check your game launcher settings. Remember to allow extra time for installation and file verification.
