What Size Disco Ball Should You Rent for Your Event?
We rent mirror disco balls in six sizes, and thinking of them as a ladder, smallest to largest, makes picking one simple:
Size should match dance floor size and ceiling height, not just room style. A bigger ball needs more clearance above it and a bigger space to fill. Hang a 36-inch ball in a modest tent and it overwhelms the room, while a 12-inch ball in a cavernous hall gets visually lost. Walk the room, note the ceiling height, and size up as the floor and room grow.
Plus Event Rentals also carries a general Mirror Disco Ball listing whose size varies by availability, so ask about current stock when you're planning.
How Does a Disco Ball Create Its Light Effect?
A disco ball is covered in small mirrored facets, and it doesn't produce any light on its own. It reflects a focused beam back out as dozens of moving points of light. As the ball turns, those points travel across walls, ceiling and guests, creating the classic scattered-sparkle effect.
Without a light source aimed at it, a disco ball is just a shiny decoration hanging in the room. A darker room makes the effect read stronger, since the moving points have more contrast to stand out against. Rotation is typically handled with a small motor; ask Plus Event Rentals which rotation and hanging options are available for the specific ball you choose. For the full lighting picture, browse lighting rentals, and if you're planning a full party, see our Company Holiday Party Rental Checklist.
What Light Do You Need to Make a Disco Ball Work?
A pin spot, a narrow, tightly focused beam, aimed directly at the ball is the classic way to light it. The Chauvet DJ EZ Pin Zoom Wireless Pin Spot Kit is battery-powered with LED pin spots, an adjustable zoom beam angle, wireless operation, and a remote control, plus rechargeable batteries. Because it runs on battery power, there are no visible cables running across the floor, which keeps the setup clean. The listing pitches it just as well for highlighting centerpieces, decor and displays as for lighting a disco ball.
Aim the beam only at the ball, dim the surrounding lights once dancing starts, and test the full effect before guests arrive so you can adjust angle and brightness. For bigger balls in bigger rooms, more than one light angle helps cover the full spread of facets and keeps the sparkle even across the space.
How Do You Hang a Disco Ball Safely?
The Mirror Disco Ball listing notes a hanging mounting point built into the ball, but where and how you hang it matters more than the hardware itself. Hang it only from a rated, venue-approved point, never from decor, ceiling tiles, tent fabric, or anything not engineered to carry weight.
Ask the venue what hanging points and rigging rules apply before you book, and confirm the ball's weight with Plus Event Rentals before you plan any rigging. Keep the ball well above guest head height and clear of anything flammable or fragile, and keep guests from standing directly beneath it while it's being hung. For general rigging safety practices, see ESTA.
If the room has no suitable overhead point, ask about staging and rigging options that can create one safely.
How Many Disco Balls Does a Space Need?
One well-lit ball in the 20- to 36-inch range usually anchors a dance floor on its own -- more isn't automatically better. Consider adding smaller accent balls, like the 12-inch mirror disco ball, over a bar, entrance or lounge area for a layered look, while reserving something like the 36-inch mirror disco ball for the main floor.
More balls demand more light sources to look good. Two balls lit by one weak light source looks worse than a single ball lit well, since neither gets enough focused beam to sparkle properly. Scale the number of balls to the room's actual layout rather than trying to fill every corner.
Where Do Disco Balls Work Beyond the Dance Floor?
Plus Event Rentals lists its disco balls for dance floors, decor and DJ use, and for weddings specifically. But, the dance floor isn't the only place they earn their keep. Consider a ball as cocktail hour decor, a backdrop behind the DJ booth, a feature piece at the entrance, or a focal point for a photo area.
Pair a disco ball with uplighting from lighting rentals to add color throughout the room while the ball supplies the sparkle; our guide to choosing uplighting for a wedding reception covers the details.

FAQ
What size disco ball do I need for a wedding dance floor?
A 20- to 24-inch mirror disco ball suits most wedding dance floors. Go with a 12- or 16-inch ball for small floors, and a 30- or 36-inch ball for large floors or big rooms. Plus Event Rentals rents mirror disco balls in 12, 16, 20, 24, 30 and 36 inch sizes to match any floor.
Do I need a special light for a disco ball?
Yes. A disco ball only reflects light, it doesn't generate any on its own. A focused pin spot aimed directly at the ball creates the moving-light effect. The Chauvet DJ EZ Pin Zoom Wireless Pin Spot Kit is battery-powered and wireless, making it a clean option with no visible cables across the dance floor.
How many disco balls should I rent for my event?
One well-lit 20- to 36-inch ball usually anchors a dance floor on its own. Add small 12- or 16-inch balls as accents over a bar, entrance or lounge for a layered effect. Each ball needs its own dedicated light source. More balls without more lighting will look worse, not better.
Can I hang a disco ball anywhere?
No. A disco ball should hang only from a rated, venue-approved point. Never from tent fabric, ceiling tiles, or decor not built to carry weight. Confirm the ball's weight with Plus Event Rentals before planning rigging, and always check with the venue about approved hanging points and rigging rules first.
What disco ball sizes does Plus Event Rentals carry?
Plus Event Rentals carries mirror disco balls in 12, 16, 20, 24, 30 and 36 inch sizes, covering everything from small accent displays to festival-scale productions. There's also a general Mirror Disco Ball listing whose size varies by availability, so it's worth asking what's in stock when planning your event.
