The best Neon signs are bold by default—but size still matters. Go too big, and it dominates the room like a stag party and wedding day. Too small, and it disappears behind your cocktail shaker. So what’s the sweet spot?
At Smithers, we’ve made neon signs for Shoreditch barbers, Ibiza beach villas, and more home offices than we can count. Here’s how to get the sizing just right for your space.
Small Neon Signs (30cm – 50cm)
Perfect for shelves, alcoves, desktops, and small shop counters. These neon signs don’t shout, but they whisper cool in all the right ways. Ideal for:
- Coffee stations
- Bedroom corners
- Retail till points
If you want subtle glow over scream, this is your zone.
Medium Neon Signs (60cm – 100cm)
This is the sweet spot for most homes and bars. They fit above sofas, beds, home bars, or salon mirrors without overpowering. Ideal for:
- Living room feature walls
- Home bar backdrops
- Studio branding
If you’re unsure, start here. It’s the all-rounder.
Large Neon Signs (100cm+)
Big, bold, unapologetic. These are built for drama. Great for wide blank walls, commercial shopfronts, events, and anyone who believes more is more.
- Shop interiors
- Event signage
- Statement restaurant walls
Just make sure your plug socket can handle the power.
How to Measure Your Space for Neon
- Measure the wall width where the sign will go
- Leave at least 15cm margin on either side
- Use painter’s tape to mark out the width and height
- Step back and see if it balances with the rest of the space
Bonus move: cut out cardboard to the exact size and pin it up. Instant preview.
Font, Phrase & Sizing: The Unseen Variables
Longer phrases = longer signs. Thicker fonts = taller letters. And cursive writing needs more room to flow. So:
- Keep it short if you’re tight on space
- Go thicker for visibility across the room
- Remember: it’s not just width—height matters too
We’ll always mock up the size for you before production. No surprises.

💬 Neon Sign Sizing – FAQs
• What’s the best size neon sign for a living room?
Go for medium (60–100cm) if you’re hanging it above a sofa, sideboard, or fireplace. It gives you presence without overwhelming the space.
• Can I use a small neon sign in a bedroom?
Definitely. A 30–50cm neon works great on shelves, above a nightstand, or tucked in a corner. It adds mood without stealing all the attention.
• How big is too big for a neon sign?
If it’s wider than your wall or fills the entire space with no margin, it’s probably too big. Leave at least 15cm of breathing room on each side to keep it balanced.
• Does the font affect the size of the sign?
Yes. Script and cursive fonts take more space because of their flow. Block fonts are tighter. Thicker fonts are also taller—so factor in both width and height.
• How do I measure my space before ordering a neon sign?
Use painter’s tape or cardboard to map out the size directly on your wall. Step back, check the proportions, and adjust before placing your order.
• Will I see the final size before production?
Always. We send you a full-size mockup based on your wall and font choice, so you’ll know exactly what you’re getting—no surprises.
