A variable stroke buffer for buffering a car or a counterweight moving in a hoistway of an elevator along a variable compression stroke comprises a buffer stand including a buffer, which is contactable by the car or the counterweight of a part of the hoistway at a decompressed position of the buffer stand and a control apparatus. The buffer stand is compressible by the buffer in a compressing direction, in which the compression stroke of the buffer stand is restricted to a compressed position, and in a decompressing direction, in which the buffer stand can decompress to the decompressed position. The control apparatus is configured to allow the compression stroke of the buffer stand in the compressing direction to a first compressed position corresponding to a first stroke, when the compression of the buffer stand is started at a first speed which is lower than a threshold speed. The control apparatus is further configured to limit the compression stroke of the buffer stand in the compressing direction to a second compressed position corresponding to a second stroke, when the compression of the buffer stand is started at a second speed which is higher than the threshold speed.
