Recent studies of  fast growing species grown in PT. Sari Bumi Kusuma, Central Kalimantan, show that based on their fiber dimensions there are five species, namely Endospermum diadenum , Dillenia spp., Adinandra dumosa , Adiandra sp., and Nauclea junghuhnii with good potential for pulp and paper production.  The fiber length of  those five wood species are was more than 2,200 µm on average. This paper studies the physical properties, fiber dimensions and their chemical contents to predict the paper and pulp quality. The result shows that all of  the species were classified in the medium to high density category. All species were classified into the first class quality for pulp and paper. Based on chemical contents, Dillenia sp. is the most suitable species due to its high value of  holocellulose and a-cellulose, low lignin content, and its fiber length is about 3,119 µm on average. A. dumosa also has good opportunities because it had the longest  fiber lengths (3,137 µm on average) and high value of  holocellulose, even though it has the highest lignin content. While Nuclea junghuhnii is  less suitable due to low values of  holocellulose and a-cellulose.
