Why is my Fortnite update size different from my friend's?

Fortnite update sizes can vary between players, even when using the same platform.

On PC, update sizes may differ based on the installation options selected in the Epic Games Launcher. For example, players who have High Resolution Textures installed may download a larger update than players who do not.

If your update size seems much larger than expected, refer to Why do download file sizes seem larger than normal, especially after an update in Epic Games Launcher?.
