You could either go with:
你可以选择：
<%= day_form.text_area :hatch, cols: "30", rows: "10" %>
or you can specify both with the size attribute:

As text area has both row and column you have to specify both
由于文本区域具有行和列，因此您必须同时指定
<%= text_area(:application, :notes, cols: 40, rows: 15, class: 'myclass') %>
For text field can use
对于文本字段可以使用
<%= text_field(:application, :name, size: 20) %>
