A study was undertaken to investigate the role of different gluing areas on the bending strength properties of wooden finger joint. Three different profiles were used in the study. It was found that the profile with the largest total tip area resulted in lowest bending strength in spite of its good finger length. The profile with shortest finger resulted in better bending strength due to its total lower tip area. It was concluded that, to get improved strength properties, the total area contributed by the finger tips involved in the finger-joint requires reduction. It was inferred that the classical approach of considering parameters of single finger needs reconsideration.
