请问儿童书桌多高比较合适?

当孩子坐在桌前时，两大臂自然下垂，桌子的托肘板正好托着两小臂，这样的桌子高度是最适合工作学习的，过去的桌子，人坐在桌前，架着人的两臂，显然是桌子过高了。 如何调整高度：在桌子的左右腿，都设有多排调节孔，将每个脚的四个螺栓松开，即可将桌子调高或调低。       下面是大有帅才学习桌根据学生身高调节桌椅高低的标准，可供参考。学习桌椅型号       桌面高       座面高     标准身高     学生身高范围         颜色标志                 1号                                         76               44               180.0               173～                               蓝                   2号                                     73               42               172.5               165～179                     白                   3号                                       70               40               165.0               158～172                   绿                   4号                                       67               38               157.5               150～164                   白                   5号                                       64               36               150.0               143～157                   红                   6   号                                     61               34               142.5               135～149                   白                   7号                                       58                   32               135.0               128～142               黄                   8号                                       55                   30               127.5               120～134               白                   9号                                       52                 29               120.0               113～127                 紫                 10号                                     49                   27               112.5               ～119                           白 收起
