Game Download Time Calculator

There is a particular kind of frustration that only gamers know: you have bought the game, cleared your evening, and the progress bar is telling you the download has hours left to run. Modern titles are enormous — 100 GB is unremarkable now — so the question “how long will this take?” matters more than it used to. Our game download time calculator answers it properly. Pick your game, enter the speed of your connection, and it works out the download time using the game’s real current size, with an honest allowance for the platform you are downloading on.

If you are not sure what speed you are actually getting, run the free test on the Speed Test UK homepage first. Use the download figure it gives you, not the number on your broadband bill, because the gap between the two is exactly why downloads disappoint. Then come back here and you will know whether tonight’s game is a tea break or an overnight job.

How to Use the Game Download Time Calculator

The calculator updates the moment you change anything, so there is no button to press. Follow these steps:

• Step 1: Pick your game. Choose from the list of popular titles, which uses the download size as of October 2026, or select “Custom size” and type any size in MB, GB or TB — handy for patches and day-one updates.
• Step 2: Enter your download speed in Mbps. Type it in, or tap one of the UK package presets if you know your package better than your test result.
• Step 3: Tell it where you are downloading. Steam and Epic usually let your line run flat out. Xbox is often a little slower, and PlayStation Network is well known for leaving a chunk of your broadband unused, so the calculator adds a realistic allowance for each.
• Step 4: Read the verdict. You get the total time, the clock time it will finish if you start now, and a plain-English suggestion — start it, start it before dinner, or leave it overnight.

How Big Are Today’s Games?

Game sizes have grown faster than UK broadband has. Textures built for 4K screens, uncompressed audio in dozens of languages and ever-larger open worlds all add up, and seasonal updates keep stacking on top. These are the download sizes the calculator uses, checked in October 2026 — treat them as close estimates, because a single patch can add or remove several gigabytes.

For anything not listed — a day-one patch, a beta, an older title — choose the custom option. You will find the size on the game’s store page or in your library before you commit to downloading, and the same maths works for films, operating system images and any other large file. Our general download time calculator covers non-gaming files with the same approach.

Why Your Download Takes Longer Than the Maths Says

The basic sum is simple: a 110 GB game is 880,000 megabits, and at 67 Mbps that divides to about three hours and forty minutes. Real downloads almost always take longer, and it helps to know why, because some of the reasons are fixable.

Bits, bytes and the divide-by-eight trap

Broadband speeds are sold in megabits per second, but your console or PC shows progress in megabytes. One byte is eight bits, so a 67 Mbps line delivers at most 8.4 MB per second. It feels like the download is crawling at a ninth of the promised speed when in fact it is running flat out. The calculator does this conversion for you and shows the MB/s figure alongside the result.

The platform holding you back

Your line is only one link in the chain. The store at the other end has to serve the file, and on a big launch night it is serving it to millions of people at once. PlayStation Network has the strongest reputation for throttling individual downloads, which is why so many PS5 owners see downloads run well below the speed their broadband manages everywhere else — Sony’s own PlayStation support pages acknowledge connection speed as a variable. Xbox is usually closer to line speed but still dips at peak times. Steam on PC is generally the most consistent, and its support site publishes live download statistics by region if you want to check whether a slow evening is just you.

Peak hours in the UK

Between about 7pm and 11pm, UK networks are at their busiest, everyone is streaming in 4K, and part-fibre (FTTC) connections in particular can sag noticeably below their daytime speed. A download started at 8pm on a Friday — which is precisely when new games unlock — can take a third longer than the same download at breakfast time. If a game offers pre-loading, use it: the files sit encrypted on your drive and unlock at release, which beats joining the queue.

Wi-Fi between the router and the console

If your console or PC connects over Wi-Fi, the wireless hop is often the slowest part of the journey, especially through walls or on the crowded 2.4 GHz band. A console in a cabinet under the TV, in the room furthest from the router, might see half the speed the line delivers. Our broadband speed test run on a phone next to the console will show you what that spot in the house actually gets.

Downloading is not the same as installing

On PlayStation especially, the progress bar has a second, quieter phase: copying and unpacking. Heavily compressed files download faster but then take time to decompress and write to the drive, and on an almost-full SSD this can be painfully slow. Keeping at least 10–15% of your drive free genuinely helps, and it is why the same game can “download” in two hours and still not be playable for another thirty minutes.

How Long Popular Speeds Take: A 100 GB Game

To give the UK packages some meaning, here is a 100 GB download — roughly a GTA V-sized title — at the speeds most households actually have, before any platform allowance:

The pattern is clear: below full fibre, big games are planned events. At gigabit speeds they become an afterthought. That is the single strongest argument for full fibre in a gaming household — not lower ping, which barely changes, but the end of overnight downloads.

How to Speed Up a Big Game Download

• Use a cable if you possibly can. An Ethernet cable from router to console removes the Wi-Fi bottleneck entirely. Even a long cable run temporarily, just for download night, is worth it.
• Download off-peak or pre-load. Overnight and early morning are the fastest windows on UK networks, and pre-loading before release day dodges the launch-night crush altogether.
• Pause everything else. A 4K stream in the next room uses around 15–25 Mbps. On a 36 Mbps line, that is most of your download gone.
• Close background downloads. Other consoles and PCs quietly pulling updates will share the line. Put them to sleep, not rest mode with downloads enabled.
• Restart the router before a big session. It clears stale connections and, on some lines, renegotiates a better sync speed.
• Mind the drive space. Leave headroom for unpacking, and delete games you have finished — modern titles make this painful but necessary.
• Check for queue behaviour on console. PlayStation and Xbox download one item at full pace rather than several slowly; queue big items one at a time.

If your download is slow because the whole connection feels sluggish and games lag once you are playing, the cause may be latency under load rather than raw speed. Our bufferbloat test checks that, and the ping tester gives you a quick read on responsiveness.

Is It Worth Upgrading Broadband for Game Downloads?

It depends how often you download. If you buy one or two big games a year and can pre-load them, a 36 Mbps part-fibre line is survivable — plan around it, and spend the money on games instead. If your household downloads something large most weeks, shares the connection with streamers and home workers, or regularly faces 20 GB patches on a Friday night, full fibre transforms the experience in a way no router upgrade can. Ofcom’s broadband speeds code of practice also gives you rights worth knowing about: if your provider consistently delivers below the minimum speed it guaranteed when you signed up, you can leave your contract penalty-free. Before paying for a faster tier, test your current speed at the times you actually download — the evening figure is the honest one to compare.

Frequently Asked Questions

How long does it take to download a 100 GB game?

On a typical UK part-fibre connection at 67 Mbps, around 3 hours 20 minutes at full line speed, and longer on PlayStation once its slower delivery is allowed for. On 36 Mbps part fibre it is about 6 hours; on gigabit full fibre, roughly 15 minutes. Use the calculator above with your own tested speed for the figure that applies to you.

Why is my PS5 download so much slower than my speed test?

Because the speed test measures your line, while the download measures your line plus PlayStation Network’s delivery, which is frequently the slower of the two. Peak-time congestion, Wi-Fi and the copying phase after the download all widen the gap. Wiring the console and downloading off-peak makes the biggest difference.

How long does Call of Duty take to download?

At around 150 GB for a full install, Call of Duty takes about 5 hours on a 67 Mbps connection, about 9 hours 15 minutes at 36 Mbps, and around 22 minutes on gigabit full fibre — before platform allowances. Remember you can uninstall parts you do not play, such as the campaign, to shrink future updates.

Does a faster broadband package reduce lag in games?

Barely. Once you have enough bandwidth for the game itself — which is usually under 1 Mbps during play — extra speed does not lower ping. Latency is about the route your data takes and how loaded your connection is, which is why a wired connection and a calm network matter more than a bigger number on the bill.

Why does the download speed keep dropping to zero?

Usually one of three things: the console is unpacking a chunk it has already downloaded (the bar pauses while the drive catches up), the store’s servers are staggering delivery on a busy launch night, or your Wi-Fi signal is dropping. If it happens on every download, test wired — if the problem vanishes, it was the wireless.

Can I download games faster by changing DNS?

Almost never in a way you would notice. DNS affects how quickly a download starts, not how fast the file itself travels. The honest wins are a wired connection, an off-peak start, and nothing else on the network competing — which is dull advice, but it works.
