Both the Xbox One (XBO) and PlayStation 4 (PS4) have been out for over two years, and each shipped with 500 GB hard drives. Since both systems require you to install every game on the hard drive, you might find your system running out of space.

We've shown you how to replace a PS4 hard drive and everything you need to know about Xbox One external drives, but if you're holding out on a storage expansion, here's some help.

Finder.com has compiled lists of install sizes for PS4 and XBO games. With over 350 titles for the XBO and 460 titles on PS4, you're sure to find whatever game you're considering. The tables contain each game's release date, size, and whether it's an AAA or independent game. PS4 games are reaching close to 50 GB for installs:

XBO games are similarly huge:

Using this list, you can figure out if a new game will fit onto your system or not. Note that these numbers are for the base installation only; most games, especially multiplayer-focused ones, will have several patches that could be gigabytes more. The numbers in the table also don't include any DLC.

Eventually you'll have to add more storage to avoid juggling games (especially with all those free PS Plus or Xbox Live Gold games), but at least you can be informed just how big new games are.

What games are you considering buying, and how big are they? Will you be upgrading your storage soon? Let us know with a comment!
