Given a positive integer s , the s -colour size-Ramsey number of a graph H is the smallest integer m such that there exists a graph G with m edges with the property that, in any colouring of E ( G ) with s colours, there is a monochromatic copy of H . We prove that, for any positive integers k and s , the s -colour size-Ramsey number of the k th power of any n -vertex bounded degree tree is linear in n . As a corollary, we obtain that the s -colour size-Ramsey number of n -vertex graphs with bounded treewidth and bounded degree is linear in n , which answers a question raised by Kamčev, Liebenau, Wood and Yepremyan.
