4.8 gb
4.7GB on a standard DVD - can be a duel layer disk (double sided) which holds 9.4GB
First off, a calrification: I am talking about a "regular" DL: disk, not a Blu-Ray disk. The capacity printed on the disk is 8.5 Gb, but some of this goes to overheads and formatting information. The useable space is more like 8.2 Gb, and can vary depending on the data being stored, e.g. movies versus data.
8.5 GB on one surface
A single-sided, single layer DVD can hold 4.7GB of data, whereas a single-sided, dual-layer can hold 8.5GB. Double-sided, single-layer holds 9.4GB and double-sided, dual-layer holds 17.1GB. So anyone of these combinations can hold a 4.7 ISO image although the single-sided, single-layer may be a tight fit. I would use the single-sided, dual-layer and you won't have any problem. An ISO is simply an exact duplicate of someting (like a Linux operating system) so you will be ok. Hope this helps.
A double-sided high-density 3.5-inch floppy disk can store up to 1.44 MB of data. This capacity is achieved by using both sides of the disk, with each side able to hold 720 KB. Floppy disks were commonly used in the late 20th century for data transfer and storage, but they have since been largely replaced by more modern storage solutions.
DVD SizesThe most common DVD type is DVD-5 (1 side, 1 layer) having 4.7GB of storage. Double-sided DVDs are rarely used.

A single DVD is capable of holding 4813 megabytes of data. Blu Ray disks, on the other hand, can hold 25600mb.
Depending on the DVD you may have: 4.7 GB (single-sided, single-layer - common) (Two hours of high quality video) 8.5-8.7 GB (single-sided, double-layer) (3.5 hours of high quality video) 9.4 GB (double-sided, single-layer) (4 hours of high quality video) 17.08 GB (double-sided, double-layer - rare) (8 hours of high quality video) Double sided disks can be written on both sides, which is why they hold about twice as much.
