Raintree Samanea saman is a multipurpose village tree species grown in abundance at southern and northern regions of Bangladesh. Village people need to know estimation procedure for timber inventory of this useful tree species. Data on diameter at breast height diameter and total height height of 205 standing sample trees were collected by Spiegel relascope for the purpose. The sample trees with diameter ranging 21 cm - 91 cm and height ranging 10 m - 20 m were considered for measurement. Volumes m3 of individual trees were computed by Smalian formula. A total of 10 linear models of volume on diameter and volume V on diameter D and height H were examined with the sample trees. A few statistics of F, t, mean square error, multiple correlation coefficient and Furnivall Index was computed and tested for investigation of best fitted models. The two models of InV = 8.3023 + 2.1746 InD and InV = –9.1864 + 1.85502 InD + 0.8234 InH were found to be best fitted models. They have been recommended to estimate volume of large scale standing Raintree trees.
