The menur's length would be roughly as long as your index finger or a little bit longer (or shorter, on your finger

). the bedor's length about 1/2 - 3/4 lenght of menur. Please remind that Javanese's bows are not as long/big as longbow. It's length are rougly 1 m only. On traditional archery competition, which still held until today in Jogjakarta Court, the competitor shoot the arrow in sitting position on the ground (duduk sila).
Please remember, I have never take any actual measurement on menur, bedor, the bow, or even the keris. all just 'roughtly', relying on my memory (which usually corrupted

) and my hand/finger which I usually use to take measurement
