The steps on a ladder are called "rungs". Rungs are the horizontal bars that run across the ladder and serve the same function as steps on a step ladder. However, in some ladder designs, especially those used in household settings or as portable step stools, the term "steps" refers to the individual platforms that you stand on while using the ladder. These platforms are typically larger than traditional ladder rungs, providing more stability and a comfortable standing surface. Unlike rungs, ladder steps are not necessarily horizontal bars but rather solid platforms that are wider and more spacious. Steps can be found on ladders such as step stools, step ladders, and platform ladders.
