OS Map File Sizes

This article details the file sizes of each of our complete map products.

Most modern PCs and Laptops are fitted with large storage drives that can store hundreds of Gigabytes (GB) of data, however we always recommend that you check your system meets the space requirements for the relevant map product you are looking to purchase.

Mobile phones and Tablets tend to have smaller storage drives and commonly use a file system that is referred to as FAT32, both of these things can restrict the amount of data that can be sent to the device.
