Here are some examples:
* Ang lapad ng kwarto ay limang metro. (The width of the room is five meters.)
* Ano ang lapad ng tela? (What is the width of the fabric?)
* Ang lapad ng kalsada ay masikip. (The width of the road is narrow.)
You can also use luwang for width, especially when talking about something spacious.
* Ang luwang ng silid ay nakakagaan ng pakiramdam. (The spaciousness of the room feels relaxing.)
However, lapad is the more general term for width in Tagalog.
