Abstract:We study the change of the conformal radiusr(U) of a simply connected planar domainU versus the subdomainU ε consisting of the points of distance at least ε to ∂U. We show that the smallest exponent λ such thatr(U)-r(U t)=0(e λ) satisfies 0.59<λ<0.91. We also show that a well-known conjecture implies 
$$\lambda  = \left( {2\sqrt {2 - 1} } \right)$$
