File sizes! What is big or small?
Sometimes it can be hard transporting files when you are not quite sure what makes a “big” file size or “small” file size.
What you should understand: Files are measured in bytes with a prefix. Bytes are the basic unit and the prefixes are multiples of the basic unit.
The exact numbers are not important, but understanding the relative size is good to know.
- KiloBytes (KB) or 1,024 bytes.
- MegaByes (MB) or 1,048,576 bytes.
- GigaBytes (GB) or 1,073,741,824 bytes.
- TeraBytes (TB) or 1,099,511,627,776 bytes
As you can see, 1GB takes up over a million bytes where as 1KB only takes up around one thousand.
The geek explanation: If you want the math behind all of this, check out Wikipedia
Typical File sizes:
Another good way to associate the different file sizes are with files you use everyday! Let’s look at the list again:
- 1-10KB A very simple text document.
- 2-15KB Text only emails.
- 20-80KB Graphic emails.
- 50-100KBs A lower resolution photo.
- 1-3MBs High Resolution Photo (one that takes up the whole screen when you open it).
- 3-8MBs MP3’s
- 10MB Standard email file size attachment limit.
- 20-150MB A low resolution video file.
- 25MB Gmail file size attachment limit.
- 700MB Size of CD-R
- 1-3GB A higher resolution video file.
- 2GB YouTube upload limit.
- 4GB Size of DVD-R
- 8-32GB Typical smart phone sizes
- 80-150GB Typical hard drive sizes
- 1TB A very large backup drive (for most people)
There is much more when it comes to compressing (making files smaller) and handling the transport of different file sizes, but understanding what makes for a big or smaller file is the best first step!
