Scribblar's bandwidth requirements are surprisingly moderate and Scribblar will therefore work fine on most consumer grade broadband connections which means a minimum upload speed of 256kbp/s and a minimum download speed of 512kbp/s.

However we recommend a minimum of 512kbp/s upload speed and 1-2mbit/s download speed for a good experience. As a rule of thumb: the more bandwidth, the better :-)

The Scribblar application itself can require a download of 2-3 MB upon first visit, but will only require a 500KB download on subsequent visits, and even less if your browser settings allow caching of content.
