What It Means

That's fine is your go-to phrase for simple agreement. It tells people you are satisfied with a plan. It is not overly excited. It is not angry. It is a calm middle ground. Think of it as a green light for a conversation. You are saying, "I accept this."

How To Use It

Use it when someone offers a solution or asks for permission. If a friend asks to meet at 5:00 PM, you say That's fine. If a waiter says they are out of fish, you say That's fine. It works best for small decisions. Keep your voice steady and light. A flat tone might make you sound bored. A smile makes it sound much warmer.

When To Use It

You can use this almost anywhere. Use it when texting to confirm a plan. Use it at work when a deadline moves slightly. It is great for polite refusals too. If someone offers more coffee and you are full, say "No thanks, that's fine." It keeps the mood friendly and easy. It is the ultimate 'low-stress' English phrase.

When NOT To Use It

Avoid this for big, exciting news. If your friend gets married, don't say That's fine. That would be very awkward! Also, be careful if you are actually upset. Saying That's fine with crossed arms means the opposite. In English, this is called being 'passive-aggressive'. If you are truly unhappy, use a different phrase to explain why.

Cultural Background

English speakers, especially in the UK and US, love being polite but indirect. That's fine is a way to avoid conflict. It helps keep things 'smooth'. It reflects a culture where we don't want to be a burden. By saying That's fine, you are telling the other person not to worry about you. It is a very helpful social lubricant.

Common Variations

You will hear people say That's perfectly fine to be extra polite. Friends might just say Fine by me. If you want to sound more modern, you can say That works for me. In very casual settings, some people just say Fine. However, be careful with just Fine as it can sometimes sound a bit grumpy!

使い方のコツ

This phrase sits right in the middle of the formality scale. It is safe for both the office and the dinner table. The biggest 'gotcha' is tone of voice—keep it upbeat to ensure you sound genuinely agreeable.
