The BibleBase Today's Bread is a Bible reading schedule based on a 3 year cycle. The OT is roughly 3 times longer than the NT, but as the Bible contains 'progressive revelation' it is best to spend equal amounts of time in each Testament. So in the 3 year cycle you will read the OT once, but you will read the NT 3 times.
