Why Modern Games Are So Big
Not long ago, a "big" game fit on a single DVD at under 9 GB. Today, a standard AAA release routinely ships at 80 to 150 GB, and some, like Call of Duty installments, push past 200 GB with updates. The culprits are familiar: 4K textures, uncompressed audio in a dozen languages, sprawling open worlds, and day-one patches that can themselves be larger than entire games from a decade ago.
That growth has a direct consequence. Buying a game digitally no longer means playing it in minutes. On a modest connection, a single download can run overnight. Knowing roughly how long you will wait — before you press the button — is the difference between gaming tonight and gaming tomorrow.

Every download time comes down to two numbers: the size of the file and the speed of your connection. The catch is that the two numbers use different units. File sizes are measured in gigabytes (GB), but internet speeds are sold in megabits per second (Mbps). One byte holds eight bits, so the conversion is straightforward:
Download time (seconds) = file size in GB x 8,000 / speed in Mbps. Example: a 100 GB game on a 100 Mbps connection takes 100 x 8,000 / 100 = 8,000 seconds, or about 2 hours 13 minutes.
That formula gives you the theoretical best case. Real downloads almost always take longer, for reasons covered below. Still, it is the fastest way to set expectations, and it is exactly the calculation the Download Time Calculator on this site performs for you — enter any file size and speed and get an instant answer.
Game Download Times by Connection Speed
The table below shows ideal download times for three typical game sizes across common connection speeds. Treat these as minimums; your actual time will be somewhat longer.
| Connection speed | 50 GB game | 100 GB game | 150 GB game |
|---|---|---|---|
| 25 Mbps | ~4 hrs 27 min | ~8 hrs 53 min | ~13 hrs 20 min |
| 50 Mbps | ~2 hrs 13 min | ~4 hrs 27 min | ~6 hrs 40 min |
| 100 Mbps | ~1 hr 7 min | ~2 hrs 13 min | ~3 hrs 20 min |
| 300 Mbps | ~22 min | ~44 min | ~1 hr 7 min |
| 500 Mbps | ~13 min | ~27 min | ~40 min |
| 1 Gbps | ~7 min | ~13 min | ~20 min |
To put those sizes in context: Fortnite sits around 30 GB, Cyberpunk 2077 near 70 GB, GTA V about 110 GB, Red Dead Redemption 2 roughly 120 GB, and Baldur's Gate 3 close to 150 GB on PC. Find your game in your library's storage page, match it to the nearest column, and you have your answer.
Platform Differences: PS5, Xbox, Steam, and Switch
The raw math is the same everywhere, but each platform adds its own wrinkles. On PlayStation 5, downloads pause automatically when a game launches, and rest mode downloads continue at full speed — many players schedule big downloads overnight in rest mode for exactly this reason.
Xbox Series X and S offer "ready to start" downloads: once the essential chunk arrives, often 20 to 40 percent of the total, you can begin playing while the rest streams in. Steam on PC is the most transparent of the bunch, showing live MB/s rates and letting you throttle bandwidth so a download does not choke your video call. Nintendo Switch, with its slower Wi-Fi chip and frequent use on hotel or shared networks, is where patience matters most — a 30 GB title can take hours on a weak signal.
One more platform quirk: consoles download patches for suspended games automatically by default. That 15 GB update you never asked for is the reason your storage keeps shrinking.
Why Your Download Is Slower Than Your Plan Promises
If the table says two hours but you are staring at five, one of these is usually responsible:
- Server-side limits. Your 500 Mbps line means nothing if the game server only feeds you 150 Mbps. Launch-day traffic makes this dramatically worse.
- Wi-Fi overhead. A "300 Mbps" Wi-Fi link rarely delivers 300 Mbps of real throughput, especially through walls or on the crowded 2.4 GHz band.
- Other devices. Someone streaming 4K video in the next room can quietly consume 25 Mbps of your pipe.
- Mbps vs MB/s confusion. Steam shows megabytes per second. Your 100 Mbps plan tops out around 12.5 MB/s — if Steam shows 11 MB/s, you are actually doing fine.
- Disk speed. On older PCs with spinning hard drives, the drive itself can bottleneck the download while it writes and unpacks data.
- Background throttling. Some ISPs deprioritize heavy download traffic during peak evening hours.
7 Ways to Download Games Faster
- Use an Ethernet cable. Wired connections are faster and far more stable than Wi-Fi for large transfers — often the single biggest improvement.
- Pause other activity. Stop streams, cloud backups, and other downloads while the game pulls down.
- Download overnight or off-peak. Servers are less congested late at night and early morning, and your own network is idle.
- Pick the nearest server region. Steam and launchers let you choose a download region — the closest one is usually fastest.
- Keep the console in rest mode. PS5 and Xbox download at full speed in rest mode without a game running to steal bandwidth.
- Move closer to the router or switch bands. If you must use Wi-Fi, the 5 GHz band is faster at short range than 2.4 GHz.
- Free up disk space first. Consoles need extra headroom beyond the game's size to unpack it; a nearly full drive can stall or crawl a download.
Quick rule of thumb: divide the game's size in GB by your speed in Mbps and multiply by 8,000 to get seconds. A 70 GB game on 200 Mbps: 70 x 8,000 / 200 = 2,800 seconds, or about 47 minutes.
Frequently Asked Questions
How long does a 100GB game take to download on 100 Mbps?
About 2 hours 13 minutes in ideal conditions. Realistically, budget 2.5 to 3 hours to account for server limits, protocol overhead, and speed fluctuations.
Why do games show download speeds in MB/s instead of Mbps?
Launchers like Steam show megabytes per second because that is the unit your operating system uses for file sizes — it makes progress easier to read. To compare with your plan's Mbps figure, multiply the MB/s number by 8.
Does downloading a game slow down my internet for everyone else?
Yes, while it runs at full speed. A game download will happily consume your entire connection. Throttle it in the launcher's settings, schedule it overnight, or use Quality of Service (QoS) on your router to reserve bandwidth for other devices.
Can I play a game while it is still downloading?
Often. PS5, Xbox Series X/S, and Steam support partial "ready to start" downloads that unlock the first playable sections early. The remainder continues in the background.
