Properties of Poplar and Basswood


Poplar and Basswood have similar structural stability, strength, fine grain, and warp resistance. Basswood is softer than Poplar, more akin to Pine in hardness. 



On average, Basswood is 8% - 10% lighter in weight than Poplar.



Poplar is the most economical of the two species, as the cost of rough lumber is lower than the cost of Basswood lumber.



Poplar is cooler overall, with a green-ish tone. Basswood has a warm, more reddish tone. 

All of our Poplar and Basswood bars and braces are fully keyable with wooden wedges. Bar and brace joints are mortised and tenoned to allow proper tensioning of the canvas while maintaining strong connections. 


We offer standard sized bars and braces in two-inch increments up to 120 inches through our online shop.
