Do Not Disturb Signs for the Office: What Works and Why

A do not disturb sign sounds simple. In practice, getting the right one for your space makes a real difference — whether you're running job interviews, therapy sessions, recording podcasts, or managing a hotel floor. This guide covers the main use cases, what to look for, and which formats work best.

Why the right sign matters

A generic "Do Not Disturb" message works for some situations. For others, being specific does more work. "Interview in Progress" tells a colleague exactly why they shouldn't knock. "Session in Progress" signals something private is happening without saying more than necessary. "Recording in Progress" warns against background noise as much as interruption.

Common wording variations for professional settings include Interview in Progress, Meeting in Progress, Confidential Meeting in Progress, Recording in Progress, Session in Progress, Training in Progress, Do Not Enter and Private. All of our signs can be personalised with custom text, so if your organisation uses different terminology, we engrave exactly what you supply.

The format matters too. A door hanger is easy to move and needs no fixings. A wall-mounted hanging sign is more permanent. A freestanding table sign works for open-plan spaces where there's no door to hang anything from.

Office and meeting room signs

The most common request we get is for interview rooms and meeting spaces. These need a sign that looks professional, is easy to swap in and out, and ideally carries your own text rather than a generic phrase.

Our Meeting in Progress Do Not Disturb sign covers the standard case — available in four sizes from small (102x74mm) up to extra large (270x190mm), with two pre-drilled holes and jute string. You can add your own text or upload a logo, so it can carry a room name, a department name, or any wording you need.

The Session in Progress sign is available with standard text or fully custom wording — useful if your organisation uses different terminology. For interview rooms specifically, the Please Do Not Disturb sign is the cleaner option if you want something that reads quietly rather than announcing the specific activity. Some HR teams prefer this for sensitivity reasons.

For open-plan offices without dedicated meeting rooms, the Quiet Please Do Not Disturb sign works as a desk or partition-mounted sign that signals focused work time without requiring a door.

All are made from 4mm oak veneered MDF. They hang from a hook or nail and come down in seconds — practical if the same room serves multiple purposes. In a professional environment, a laser-engraved wooden sign looks deliberately chosen rather than an afterthought, and the engraving is permanent — it won't fade, peel or become illegible over time.

Interview in progress signs

"Interview in Progress" is one of the most searched sign phrases we see, and for good reason. It communicates authority and privacy in a way that a plain Do Not Disturb sign does not. Anyone passing knows exactly what is happening and why they should keep their distance.

We make these as part of our personalised wooden signs range — laser engraved on oak veneer, personalised with any wording. If you need it to say "Interview in Session" or "Interviews Ongoing — Please Wait" or just "Interview Room", we can engrave exactly that via the custom text sign.

Four sizes means the sign scales to the door or wall. The extra large (270x190mm) reads clearly from several metres away, which is useful in open corridors.

Therapy, counselling and wellness spaces

Therapy rooms have specific needs. The sign needs to be visible and clear, but ideally not alarming or clinical in appearance. A wooden sign reads warmer than a laminated card. "Session in Progress" is the most common phrase used — it conveys privacy without clinical language.

Our Please Do Not Disturb hanging sign works well here. Some therapists add a subtitle like "Please wait quietly in the waiting area" — this is easy to include in the personalisation box at checkout. The Privacy Please door hanger is a softer alternative — a smaller, more discreet format that suits therapy and wellness contexts where "do not disturb" might feel too abrupt.

Meditation, yoga and wellness rooms

Wellness and mindfulness spaces benefit from signage that matches the tone of the room rather than using blunt corporate language.

The Meditation in Progress sign is our most popular mindfulness sign, available in four sizes in oak and also in FSC-certified bamboo for spaces where natural materials matter. The Yoga Session Do Not Disturb freestanding sign is a solid oak freestanding plaque — suitable for yoga studios, wellness rooms and home practice spaces where you want a sign that sits in the space rather than hanging on the door.

Recording and broadcast spaces

Podcast studios, voiceover booths, video call rooms and broadcast spaces all need a sign that signals both privacy and silence. "Recording in Progress" or "On Air" sets the right expectation — it tells people that noise matters, not just presence.

The Meeting in Progress sign can be personalised with any wording including "Recording in Progress", "On Air" or "Live Session". The logo upload option is useful if you want to include a station name or studio brand.

Home office and bedroom signs

Working from home has created real demand for this category. A door sign that tells housemates or family members that a call is in progress is genuinely useful — and a wooden sign is considerably more considered than a Post-it note.

The Working From Home — Do Not Knock sign is designed specifically for this, and the Do Not Disturb door hanger is a simpler alternative in a smaller format that suits a home door rather than a commercial one. The Please Do Not Disturb hanging sign in the small or medium size also works well — some customers personalise it with "Working — Do Not Knock" or "On a Call" for clarity.

Two related home signs: the Baby Sleeping Do Not Knock sign for new parents, and the Night Shift Worker Sleeping sign for front doors and communal entrances — a clear message for delivery drivers, neighbours and visitors that the occupant works nights.

Hotel door hangers

Hotels are a different use case. The sign needs to be physically hung on a door handle rather than mounted to a wall, and it needs to work for the full range of guests — so double-sided (Do Not Disturb one side, Please Service My Room the other) is the standard format.

We make hotel door hangers in oak and bamboo, covering standard and wide handle holes, rounded and rectangular tops. Bamboo is slightly more moisture-resistant, which makes it the better choice for rooms with en-suites. Both can be engraved with your hotel name or logo. See our complete hotel door hangers guide and the hotels and hospitality collection.

Bulk orders from 20 units get automatic discounts — 10% at 20, rising to 35% at 1,000. No discount code needed at checkout.

Which format is right for you?

• Door hanger (slotted over the handle): best for hotel rooms, rental properties, any space where you want zero fixings and easy removal.
• Hanging sign (two holes, jute string): best for offices, therapy rooms, interview rooms — hangs from a hook or nail, easy to take down.
• Freestanding sign: best for open-plan offices, reception desks, or anywhere there is no door — sits on a desk, counter or shelf.

Size guide

• Small (102x74mm) — home doors and private offices where something discreet is preferred
• Medium (155x115mm) — the most popular size for commercial and office doors
• Large (225x164mm) — high-traffic corridors or anywhere the sign needs to be noticed at a distance
• Extra Large (270x190mm) — maximum visibility, well-lit public areas, large entrance doors

Personalisation options

Every sign we make is personalised to order. That means you can specify exact wording, add a logo, include a room name or number, or combine a standard phrase with your own subtitle. There are no minimum quantities on single items, and bulk discounts start automatically from 20 units — useful for fitting out a full office building, a therapy suite, or multiple meeting rooms consistently.

Logos should be uploaded as PNG or JPG. Black and white artwork engraves most clearly, though colour logos usually work well too.

All signs are made to order in our workshop in North Wales and dispatched via Royal Mail Tracked 24 for UK orders.
