The 2006-2010 Toyota Yaris wiper blade sizes are 26" drivers side, 14" passenger side and a fairly specialized 12" rear wiper that is difficult to find in the stores. See sources and related links below for more information. Since there are currently over 22 different wiper arm attachments, do not buy wipers just by length only - be sure to lookup exact wiper blade part numbers by vehicle make, model and year for the brand wiper you decide to purchase. This ensures correct length AND correct attachment.
According to my reference, there was no 2004 Toyota Yaris but there is a 2004 Toyota Echo. (The Yaris replaced the Echo in 2006). See sources and related links below.
