Measure the working space, not only the gap for a counter.
A mobile bar can fit across a wall and still leave too little room to use it. Your space plan needs four parts: the frontage guests see, the working area behind it, supplies and returns, and a clear approach. Measure those areas together before finalising tables or a dance floor.
Start with frontage
Cocktailhire uses one 1.5-metre bar unit per 100 guests as its planning baseline. For 150 guests, that becomes two units and 3 metres of frontage. That does not mean a 3-metre-wide strip is sufficient. The team also needs usable depth, a way to restock and room to handle glasses.
A floor plan you can send
- Mark the proposed bar position and the available width and depth.
- Show doors, exits, tables, furniture and the dance floor.
- Mark where supplies and used glasses can sit without obstructing staff.
- Draw the unloading route, including narrow doors, lifts, stairs and changes of level.
- Show water and power access where available.
There is no single honest floor-area allowance that suits every bar configuration. Send the measurements for the actual room so the selected setup can be assessed. For a garden or marquee, include the ground surface and a sheltered alternative, not just the sunny-day position.
Compare the available setups on mobile bar hire, or send your floor plan and event details. The free drinks calculator helps with quantities; it does not certify that a bar fits the room.
