Bandwidth and capacity can both describe a limit. Their scope and tone often differ.
Capacity means how much a person, team, or system can handle. At work, bandwidth often means available time and focus. In networking, it can mean a data-rate or frequency-range limit.

Learn "Bandwidth" in depth →Choosing the right word for the moment
Bandwidth fits many informal requests about time or focus. Capacity often fits plans, staffing, and service limits. Still, context matters more than a strict formality rule.
Internal Slack message: "Do you have bandwidth to look at this today?"
Planning document: "Current team capacity supports two concurrent launches."
Client email: "We're assessing delivery capacity for the next phase."
The audience changes, but so does the focus. The first asks about one person's available attention. The other two describe planned delivery limits. "Delivery capacity" may sound formal in a quick chat. "Bandwidth for two concurrent launches" can work internally, but it is less exact in a firm plan.
Use this as a guide: bandwidth often points to time and attention ("do you have bandwidth"). Capacity often points to a planned limit ("our capacity supports"). Check the meaning, audience, and level of precision.

Start the "Bandwidth" learning path →The common mistake: using bandwidth where capacity fits better
Mistake: using bandwidth in a plan when capacity would state the limit more clearly.
"Bandwidth" may sound vague in a board memo or client plan. It is not always wrong. Yet the reader may ask whether it means staff time, network limits, or another resource. Use capacity when you can name and measure the planned limit.
