A monogram on the dance floor is one of the most photographed details at a wedding, and it is also one of the simplest to get wrong. The image comes out too small, it lands on a dark carpet, or guests stand in the beam and wear the logo on their faces. This guide explains how it works so you can plan it.

What a gobo is

The word comes from "goes before optics." A gobo is a thin disc, usually metal or glass, with a pattern cut into it. It sits in front of the lamp inside the fixture. A lens focuses the pattern onto a surface. A metal gobo gives a crisp one-color image. A glass gobo can show color or fine detail, and costs more.

Other projection options exist: an LED projector that can show custom images or a short video loop; a rented digital projector; and lasers. A static gobo is the most common choice for a monogram.

Gobo projection size by throw distance A light fixture on a stand at left projects a cone onto a floor. At a 10 foot throw the image is small, at 20 feet it is larger. A person standing in the beam casts a shadow and blocks part of the image, so the fixture should be mounted high and to the side. 10 ft 20 ft Fixture at 10 ft high
The farther the fixture is from the floor, the larger the image.

Choosing the size

There is no one size. The vendor calculates it from the fixture's lens and the throw distance. Lenses differ a lot, so a fixture at 12 feet can throw a small circle or a wide one. Ask for a specific diameter and an angle that the vendor has tested.

Surface Works Notes
White or light vinyl dance floor Yes, best Bright and smooth
Wood floor, light Yes Matte finish is better than glossy
Dark wood or black floor Weak Needs a very bright fixture
Carpet Poor Texture breaks up the image
Grass Poor Uneven surface
White wall or backdrop Yes Keep the fixture level to avoid distortion
Tent sidewall Fair Fabric colors and folds show

A rented white or light-toned dance floor is the most reliable surface. A high-gloss floor can reflect the fixture itself and wash out the image.

Where to mount the fixture

  • High and straight down gives the cleanest, least distorted circle, but needs a truss, ceiling point or tall stand.
  • At an angle from the side is easier but stretches the image. Pick an angle with the vendor and keep the logo's text readable.
  • Behind the DJ works for wall projections.
  • Away from the dance floor. Guests dancing between the light and the floor block the beam. Raising the fixture reduces shadows.

If the venue allows no rigging, ask for a tall freestanding stand. See the rigging notes in pin spot lighting, which has the same rigging questions.

Designing the artwork

Good monograms are simple. Thin lines and tiny text can blur at a distance.

  • Use bold, high-contrast shapes with generous spacing.
  • Limit the design to initials, a date or a short name.
  • Avoid very thin script that disappears at 10 feet.
  • Provide a vector file (an AI, EPS or SVG file) or a high-resolution black-and-white image.
  • Ask for a proof before the vendor builds the gobo.

Typical timeline: custom gobos are made to order, so ask for the vendor's lead time at booking. Do not wait until the last week.

Brightness and room light

A projection needs a dim room. Candles are fine, but bright uplights, a spotlight or sunlight through a tent wall wash it out. Choose the moment: first dance, grand entrance and last song. Turn the pattern off when the dance floor turns into a party. Combine with LED dance floor lighting in a way that does not fight the monogram.

  1. 1Step 1Choose the surfaceand confirm it is light and smooth.
  2. 2Step 2Measure the throw distanceand mounting options.
  3. 3Step 3Send simple artworkand approve a proof.
  4. 4Step 4Test at nightwith the lights dimmed.
  5. 5Step 5Mark the focusso it stays sharp after load-in.

Power

A gobo light draws modest power. LED fixtures use less than older halogen ones. Plan an outlet near the mount, and see the event power needs checklist.

Chicago notes

Chicago's older ballrooms and historic venues sometimes ban stands or taping on the floor. Ask your venue about rigging, floor protection and who may run the fixture.

Frequently asked questions

What is a gobo?

A gobo is a small stencil placed inside a light so it projects a pattern, like a monogram, onto a surface.

How big will my monogram be?

It depends on the distance and lens. Ask your vendor for the diameter at your mounting height.

Can I project on grass?

It is possible but looks poor because the surface is uneven. Use a dance floor or a white mat.

How far in advance should I order a custom gobo?

Ask the vendor for their lead time when booking. Custom items need time for design, proofs and production.

Does a monogram work in a tent?

Yes at night with a light floor. Daylight and uplights wash it out.

Can I change the monogram during the event?

Not with a static gobo. Digital projectors can show changing images.
