梯段净宽除应符合防火规范的规定外，供日常主要交通用的楼梯的梯段净宽应根据建筑物使用特征，一般按每股人流宽为0.55＋(0～0.15)m的人流股数确定，并不应少于两股人流。楼梯平台上部及下部过道处的净高不应小于2m。梯段净高不应小于2.20m。
希望我的回答对你有帮助

踏步数不超过18级不少于3级，高不大于180，宽不小于260，符合人流宽度，休息平台净深大于梯度宽，踏步净高不小于2200，平台梁净高不小于2000.看楼层高度，看设计成几跑楼梯，看房屋的开间尺寸，综合踏步数确定踏步和梯步尺寸，符合规范就行了。
希望我的回答能帮到您，谢谢您，望采纳

规范：

　　1、为减少人们上下楼梯时的疲劳和适应人们行走的习惯，一个楼梯段的踏步数要求最多不超过18级，最少不少于3级。

　　2、住宅建筑应尽量减小梯井宽度，以增大梯段净宽，一般取值为100～200mm。公共建筑梯井宽度的取值一般不小于160mm，并应满足消防要求。

　　3、栏杆(栏板)和扶手是楼梯段的安全设施，一般设置在梯段和平台的临空边缘。要求它必须坚固可靠，有足够的安全高度，并应在其上部设置供人们的手扶持用的扶手。在公共建筑中，当楼梯段较宽时，常在楼梯段和平台靠墙一侧设置靠墙扶手。
