Event Floor Plan Software That Works to Scale
A drag-and-drop event floor plan creator where a metre on your screen is a metre in the room to draw the perfect event layout.

Four Ways to Hand It Over
Give access in the software, send it with a briefing, open it in the app, or export a PDF. Most events use more than one.
Give Access to the Room, Not the Guest List
Your venue contact needs the floor plan. They do not need to know who is coming.
-
Set floor plan access per person.
-
Choose no access, read, or manage.
-
Seating guests still needs your ticketing right.
-
Let a venue or production contact draw too.
Send It With the Briefing
The plan travels with the instructions your suppliers already get, so it is not a separate thing to chase.
-
Attach the plan to a supplier briefing.
-
It arrives with the rest of their instructions.
-
Open it in the app while you are on site.
-
Everyone with access sees the current version.
Or Hand Over a Real Document
For the people who will never log in: a plan to email, print and pin up on the day.
-
Download the layout as a PDF.
-
Print it straight from your browser.
-
Text and lines stay sharp at any zoom.
-
A scale bar lets anyone measure the print.
From Event Diagram to Who Sits Where
Draw the room for its own sake, or keep going: the chairs you have already drawn can take names. Assign your guest list to them, or let ticket buyers pick their own, in our event seating plan software. It is the same canvas, so nothing has to be drawn twice.
Conferences and Dinners
Lay out the room, check the gangways, and send the venue a plan they can build from.
Parties and Receptions
Put the bar, the buffet and the dance floor down first, then fit the rest around how people move.
Load-in and Safety
Show crews where things go, and mark the entrances and emergency exits on the plan.
Connected to Everything
Your layout lives beside ticketing, guest registration, briefings, suppliers and the rest of your event.
Frequently Asked Questions
-
What is event diagramming software?
Event diagramming software lets you draw the layout of an event on screen instead of on paper or in a slide deck. You set the real dimensions of the room, then place tables, stages, bars, walls and doors on a canvas that keeps everything to scale. The result is a floor plan your venue and suppliers can measure and build from, rather than a picture that only looks about right.
-
How do you make an event floor plan?
Start with the room. Set its width and depth in metres, or upload the venue's own floor plan and set the scale by clicking two points a known distance apart. Then drag in what the event needs: tables and seat rows, a stage, a bar, walls and decor. Check the gaps with the measure tool, add dimension markers where they matter, and export the finished plan as a PDF for everyone who has to build it.
-
Can I draw a floor plan to scale?
Yes. Everything is drawn in real metres, so a two metre bar takes up two metres of floor. You can measure any distance on the plan, drop dimension markers that stay visible and print with it, and see the live gap to the nearest objects while you drag something. The exported PDF carries a scale bar and the room size, so anyone can measure straight off the print.
-
Can I upload my venue's floor plan and draw on top of it?
Yes. Upload the drawing the venue gave you as a PDF, PNG or JPG and it sits underneath your plan as a background layer. Click two points you know the real distance between, type that distance, and everything you draw on top is to scale. It is the fastest way to get a plan that matches the actual building rather than an approximation of it.
-
What can I put on an event layout?
Round tables, long tables, standing tables and seat rows for theatre-style setups. A bar, a buffet, a stage and a dance floor. Zones you name yourself, which is how you mark a DJ booth, a cloakroom or a storage corner. Draw the room itself too: straight walls, curved walls, rounded corners, and doors you add straight into the wall. Plants and decor, entrances and emergency exits, free passages to keep gangways clear, plus your own text labels and dimension markers. Everything is placed in real metres and every size can be changed.
-
Is the event floor plan creator 2D or 3D?
It is a 2D floor plan, seen from above, the same way a venue or a fire officer reads a room. That is deliberate. A flat plan drawn to scale is what a caterer, a stage builder and a venue manager actually work from, and it takes minutes rather than an afternoon to produce.
-
How do I share the plan with my venue and suppliers?
Four ways, and you will use more than one. Give people access to the event itself, so they open the current plan rather than a copy of it: floor plan access is set per person as no access, read, or manage, separately from your guest list, so your venue contact can be given the room without the names of the people in it. Open it in the app when you are standing in the venue. Attach it to an event supplier briefing, so it goes out with the rest of their instructions. Or export it as a PDF and print it for the crew working the room.
-
Is there an alternative to Cvent Event Diagramming?
If you are comparing tools, the short version is that eventplanner.net is browser-based, takes minutes to learn, and needs no demo call or enterprise contract to get started. You can create an account and explore the event software for free; the diagramming canvas is part of eventplanner.PRO, with pricing published on the event software pricing page instead of quoted on a call. We set the two side by side on our Cvent alternatives page.
-
Do I need to install anything?
No. The whole thing runs in your browser, on desktop and on mobile. There is nothing to install, and no file to email around, because the plan lives with the event and everyone with access sees the current version.
-
Can I use the same plan to seat my guests?
Yes, and this is the part a standalone drawing tool cannot do. The chairs you draw can take names: assign your guest list to them yourself, or let ticket buyers choose their own seat while they order. It is the same canvas and the same plan, connected to your guest list, tickets and check-in. See our event seating plan software for how that side works.
-
How big a venue can one plan handle?
A single plan comfortably covers venues up to around two thousand seats, which is the vast majority of dinners, conferences, receptions and mid-size shows. The canvas stays responsive as the layout grows, and you can zoom and pan around a large floor without it slowing down.
