How to set boundaries

Types of boundaries

There's no official list of boundary types, but grouping them by what they protect makes them easier to spot in your own life. These are the main types you'll see described:

• Emotional boundaries: protecting your feelings and energy, such as not taking responsibility for someone else's mood.
• Physical boundaries: your body, personal space and privacy, including who touches you and how.
• Time boundaries: how your hours and rest are spent, and how much of them you give to others.
• Material and financial boundaries: your money and belongings, and what you'll lend, give or share.
• Digital boundaries: your phone, messages, passwords and privacy online.
• Sexual boundaries: what you do and don't consent to, including the right to change your mind at any point.
• Intellectual and values boundaries: your thoughts, beliefs and opinions, and how you expect them to be treated when someone disagrees.

Work and family aren't separate types so much as places where several of these show up at once. You may find one or two types much harder to hold than the others, and that's a useful place to start. If someone pressures you past a sexual boundary, that is never okay: in England and Wales you can call the Rape Crisis 24/7 Support Line on 0808 500 2222, and in the US the RAINN National Sexual Assault Hotline on 1-800-656-4673. In Scotland, Rape Crisis Scotland is on 08088 01 03 02. If you're in immediate danger, call 999 (UK) or 911 (US).

Examples of healthy boundaries

Here are some plain, everyday examples. Each one describes something you do, not something you make the other person do.

Emotional boundaries protect your feelings and energy:

• Not taking on responsibility for fixing someone else's mood.
• Saying you can't talk about something heavy tonight, and offering another time.
• Leaving a conversation when it turns to shouting or name-calling.

Time boundaries protect your hours and rest:

• Keeping one evening a week free of plans, and treating it as booked.
• Leaving a gathering at the time you said you would.
• Saying no to a favour when your week is already full, without a long excuse.

Physical boundaries protect your body and space:

• Choosing whether to hug, kiss or shake hands, and saying so.
• Asking people to knock before coming into your room.
• Not lending your car, clothes or other belongings if you'd rather not.

Digital boundaries protect your attention and privacy:

• Turning off message notifications after a set time each night.
• Not sharing your passwords or location, even with people close to you.
• Asking friends to check before posting photos of you or your children.

At work, boundaries protect your job from swallowing the rest of your life:

• Not checking work email at weekends, and saying so in advance.
• Asking which task should come first when you're handed one more.

There is more on this in the guide to setting boundaries at work.

With family, boundaries protect your adult choices:

• Choosing which parts of your relationship, health or money you discuss at family events.
• Agreeing visit lengths in advance, such as two nights rather than a week.
• Making parenting decisions with your partner, and politely holding them when relatives disagree.

Material and financial boundaries protect your security:

• Deciding a limit on what you'll lend, and sticking to it.
• Not paying for other adults' bills as a matter of course.
• Keeping some savings that are yours alone, even in a shared household.

And here are some example phrases for saying them. Keep them short:

• 'I'm not able to talk about this tonight. Can we pick it up tomorrow?'
• 'I'd rather not hug, but it's lovely to see you.'
• 'I don't check work messages after 7pm. If it's urgent, please call.'
• 'I'm not able to lend money, but I'm happy to help you look at your options.'
• 'We're staying two nights this time. We're really looking forward to it.'
• 'Please ask me before you post photos of the kids.'

Work boundaries in particular have been studied directly. In two qualitative studies of how people manage the line between work and home, Glen Kreiner, Elaine Hollensbe and Mathew Sheep found four kinds of 'boundary work' tactics: behavioural, temporal, physical and communicative. In plain terms, what you do, when, where, and what you tell people. Their model suggests these tactics can ease the strain when work and home pull against each other.

Signs you need better boundaries

A missing boundary rarely announces itself. It usually shows up as a feeling first. You might recognise some of these:

• You often feel resentful after saying yes.
• You dread certain calls, messages or visits, even with people you love.
• You feel responsible for keeping everyone else happy.
• You over-explain or apologise when you do say no.
• Your plans, rest or money keep getting given away.
• You feel guilty for wanting time to yourself.
• People seem surprised, or annoyed, when you do push back, because you rarely have.

Resentment is one of the most useful signals here. It often points to a place where you've been giving more than you want to, and where a clear limit would help both of you.

Why setting boundaries feels so hard

If saying no makes your heart race, you're not doing it wrong. A boundary can feel like a risk to the relationship: the other person might be hurt, angry, or think less of you. If you grew up keeping the peace, or your worth feels tied to being helpful, holding a line can feel selfish even when it's fair.

That's why boundaries and people-pleasing are two sides of the same coin. People-pleasing is the automatic yes; a boundary is the honest no, or the honest 'yes, but only this much'. If the yes comes out before you can stop it, the guide to stopping people-pleasing is a good place to start alongside this one.

Guilt after a fair boundary doesn't mean you were wrong. It may simply be the old habit protesting. For many people it fades as the boundary becomes normal.

How to set a boundary, step by step

You don't need a big speech. You need to know what you want, a few clear words, and the willingness to follow through.

One exception first. If a partner or family member is controlling, threatening or violent, setting a boundary with them can make things more dangerous. Talk to a domestic abuse service before you do: in England, the National Domestic Abuse Helpline on 0808 2000 247; in Scotland, 0800 027 1234; in Wales, 0808 80 10 800; in Northern Ireland, 0808 802 1414; in the US, the National Domestic Violence Hotline on 1-800-799-7233.

1. 1Notice the signal. Resentment, dread or exhaustion around a person or situation is often the first sign a limit is missing.
2. 2Decide what you will do. Write the boundary as your own action: 'I'll leave at 10pm', not 'they have to stop keeping me late'.
3. 3Choose your words. Say what's happening, how it affects you, what you're asking for or saying no to, and why it helps. Keep it short and kind.
4. 4Say it early and calmly. A boundary lands better at a quiet moment than in the middle of an argument.
5. 5Follow through. If the line is crossed, do what you said you'd do. The follow-through is the boundary; the words just announce it.
6. 6Expect some pushback, and let the guilt pass. People who benefited from you having no limit may test the new one. Stay kind, and stay consistent.

Step 3 draws on DEAR MAN, a skill from Marsha Linehan's dialectical behaviour therapy (DBT) for asking for what you want. You describe the situation, express how you feel, assert what you want, and reinforce it by saying why it helps. Meanwhile you stay on topic, sound confident and stay willing to negotiate. The steps also draw on assertiveness training, which a 2018 review by Brittany Speed, Brandon Goldstein and Marvin Goldfried called 'a forgotten evidence-based treatment'. The review notes that research on it has dropped off sharply, so much of the evidence is older.

Here's what that can look like. Say your sister calls every evening during dinner and stays on for an hour. You decide your boundary: you'll talk after the children are in bed. At a calm moment you say, 'I love our calls, but dinner is chaos here. Can we talk after 8 instead? I'll be able to give you my full attention.' When she rings at 6.30 the next day, you answer briefly: 'It's dinner time, I'll call you at 8.' Then you do.

The free worksheet below walks you through these steps for one boundary of your own, so you finish with the exact words and a plan for what you'll do if it's crossed.

What to say: boundary scripts you can adapt

These are starting points, not lines to recite. Change the words until they sound like you.

• With a parent: 'I know you worry, and I'm glad you care. I'm not going to talk about my relationship at family dinners. If it comes up, I'll change the subject.'
• With a partner: 'I want our evenings to feel like time together. Can we keep phones away during dinner? I'll do the same.'
• With a friend who borrows money: 'I care about you, and I can't lend money any more. It's been putting a strain on me. I'm happy to help you think it through, though.'
• At work: 'I can take this on, but not by Friday alongside the report. Which would you like me to do first?'
• With yourself: 'I've said I'll stop work at 6, so I'm closing the laptop now, even though there's more to do.'

Notice what these have in common. Each one is short, says what you will do, and leaves the other person's dignity intact. None of them needs a long justification. The more you explain, the more it sounds like the boundary is up for debate.

What to do when someone ignores your boundary

Some people will test a new boundary, especially if they're used to you having none. That doesn't mean it failed. It means it's new.

• Repeat it once, calmly and briefly. 'Like I said, I'm not discussing that.' No new arguments needed.
• Follow through with your own action. Leave the conversation, end the call, hand the task back.
• Notice the pattern. If someone keeps crossing the same line after you've been clear, that tells you something about the relationship, not about whether your boundary was fair.
• Adjust how close you are, if you need to. You can see someone less, share less, or rely on them less, without a dramatic falling-out.

One important exception. If a partner or family member is controlling, threatening or violent, setting a boundary can make things more dangerous, not less. In that situation, talk to a domestic abuse service before you act. In England, the National Domestic Abuse Helpline is on 0808 2000 247. In Scotland, call 0800 027 1234; in Wales, 0808 80 10 800; in Northern Ireland, 0808 802 1414. In the US, the National Domestic Violence Hotline is on 1-800-799-7233. If you're in immediate danger, call your local emergency number.

When to get more support

Boundaries can be hard to hold on your own, especially if they bring up old fears of rejection or conflict, or if anxiety or low mood make every conversation feel high-stakes. That's not a failure. It's a sign this is worth working on with someone.

A GP is a good first step and can point you towards talking therapies. Assertiveness is something therapists often help with, and a therapist can help you practise the conversations before you have them. If things feel heavy, you deserve real support, not just a page to fill in.
