Neon sign size guide: how big should your sign be?

The most common sizing mistake is choosing a width first and then trying to fit the words into it. It works better the other way around: start with your text, find the smallest width that holds it, then check that width against the wall and how far away people will be. This guide walks through those steps, with size charts and examples for common rooms. When you are ready, the size guide page and the neon designer let you try it with your own words.

How we measure a neon sign

• Width is measured left to right across the widest line of the design. It is the number you choose when you order, from 20 to 120 in.
• Height follows from your text and font. A one-line name is short and wide; each extra line makes the sign taller. The designer shows the height as an estimate as you type.
• Depth is small: the standard clear acrylic backboard is 6 mm (about 1/4 in), and wall standoffs float it about 1 in off the wall.

Not every maker measures the same way. Some quote the longest side of the sign, which on a tall design is the height. When you compare sizes, check what the number means. Ours is always the width.

Step 1: Count the characters on your longest line

A width allows about 1 character, spaces included, per 2 in of width on the longest line. So 10 characters need at least 20 in, and 18 characters need at least 36 in. Shorter lines above or below fit inside the same width, so two or three lines hold more words at the same width.

Width	One line	Two lines, in all	Three lines, in all	Good for
20 in (51 cm)	up to 10	up to 20	up to 30	A short name, one word, a desk sign
24 in (61 cm)	up to 12	up to 24	up to 36	A name, a nursery wall
30 in (76 cm)	up to 15	up to 30	up to 45	Two short names, a short phrase
36 in (91 cm)	up to 18	up to 36	up to 54	Wedding names, a bedroom, a home bar
42 in (107 cm)	up to 21	up to 42	up to 63	Above a queen bed, a salon wall
48 in (122 cm)	up to 24	up to 48	up to 72	A wedding backdrop, a bar back wall
54 in (137 cm)	up to 27	up to 54	up to 81	Above a large sofa or a king bed
60 in (152 cm)	up to 30	up to 60	up to 90	A long phrase, an event backdrop
72 in (183 cm)	up to 36	up to 72	up to 108	A business wall, a large event
84 in (213 cm)	up to 42	up to 84	up to 126	A long name wall, a stage
96 in (244 cm)	up to 48	up to 96	up to 144	A large logo wall, a venue
120 in (305 cm)	up to 60	up to 120	up to 180	The biggest walls and events

Counts are characters with spaces; on two or three lines, each line holds up to the one-line count. Script and block fonts take slightly different room, and our guide to the best fonts for neon signs shows how the choice changes the look.

A useful trick: split long phrases

Because the size follows the longest line, splitting a phrase onto two lines makes the letters bigger at the same width. “Happily Ever After” on one line is 18 characters and needs 36 in. As “Happily / Ever After” the longest line is 10 characters, so a 36 in sign shows much larger letters, and the sign gets taller. You can type up to 3 lines in the designer.

Size groups at a glance

Group	Widths	Typical places
Small	20 to 24 in (51 to 61 cm)	Desk, shelf, bar top, a name over a crib or a bed
Medium	30 to 42 in (76 to 107 cm)	Bedroom, living room, home bar, salon, wedding names
Large	48 to 60 in (122 to 152 cm)	Wedding backdrop, above a large sofa, bar back wall
Extra large	72 to 120 in (183 to 305 cm)	Business walls, stages, events, big storefronts

Step 2: Check the width and height against your wall

A sign that is too small looks lost; one that is too big crowds the room. Two rules from picture hanging work well for neon too.

1. Over furniture, aim for about two thirds of its width. If your sofa is 84 in wide, two thirds is 56 in, so a 54 or 60 in sign looks balanced. The same rule works over a bed, a console table or a back bar.
2. On an empty wall, hang the centre at about eye level. A common guide is about 57 in from the floor to the centre of the piece. Above furniture, hang it a little above the furniture instead, so the two read as a group.

Check the height you have as well: the space between a headboard and the ceiling, under a shelf, or inside a window frame. A second or third line makes the sign taller at the same width. Leave some clear wall on each side so the glow has room. For the hanging itself, see how to hang a neon sign.

Step 3: Think about viewing distance

A sign maker’s rule of thumb is about 1 in of letter height for every 10 ft people will read it from.

Reading distance	Smallest comfortable letter height	Typical place
10 ft	about 1 in	Bedroom, desk, small office
20 ft	about 2 in	Living room, salon, wedding tables
30 ft	about 3 in	Bar back wall, restaurant, shop window from the sidewalk
50 ft	about 5 in	Large venue, stage, warehouse wall
100 ft	about 10 in	A storefront seen across a parking lot

Script lowercase letters read smaller than block capitals of the same height, so go a size up for script seen from far away. In the designer, pick the width whose estimated height gives letters at least that tall. If one long line gives letters that are too short, split it onto two lines or go up a width.

Examples by room and use

Weddings

Spot	Width to start from
Cake, dessert or bar table	20 to 30 in, standing on a clear base
Welcome table or entrance	24 to 36 in
Sweetheart table or flower wall	36 to 48 in for names, up to 60 in for a phrase
Dance floor, stage or a large hall	60 in and up

“Emma & Noah” is 11 characters, so it needs at least 22 in; at 36 in the names are larger and easier to read from the tables. Our wedding neon sign guide covers color and timing, and the custom wedding neon sign has the designer set up for names.

Bedrooms and kids’ rooms

A queen bed is 60 in wide, so about 40 in suits it; a 36 or 42 in sign fits. A king bed is 76 in wide, so about 50 in, which means a 48 or 54 in sign. For a single name, 6 to 8 letters fit a 20 to 24 in name sign. In a child’s room, mount it high and out of reach, and keep the adapter and cable away from the crib or bed. See neon signs for bedrooms for more ideas.

Living rooms, home bars and bars

Above a sofa, two thirds of the sofa width is the starting point; on a gallery wall or over a shelf, 30 to 36 in holds its own. Behind a home bar, 30 to 48 in suits a short word or phrase. In a bar or restaurant, measure from the farthest table and use the distance table. Our bar neon signs come in widths from 20 to 60 in.

Businesses and shop windows

A logo behind a reception desk often looks right at about two thirds of the desk width. In a window, think about the sidewalk: someone 30 ft away reads letters of about 3 in comfortably. Our guide to neon signs for business goes through logos, windows and outdoor signs.

Desks, shelves and counters

The tabletop neon sign comes in 20, 24 or 30 in widths and stands on a clear 8 mm acrylic base that is shorter than the sign and sits centred under it.

Common sizing mistakes

1. Choosing the width before the words. Write the text first, then size it.
2. Forgetting spaces and symbols. Every space counts as a character, and so does an &.
3. Measuring the width but not the height above a headboard, under a shelf or in a window.
4. Ignoring reading distance. A sign read from across a bar needs bigger letters than one above a bed.
5. Comparing numbers that mean different things. Check whether a size is the width or the longest side.
6. Forgetting the outlet. Plan where the adapter plugs in and how the cable runs.

Before you order

• Mark the width and height on the wall with painter’s tape and look at it from where you will usually stand.
• Check where the nearest outlet is. A DC extension cable can add distance.
• Type your words into the designer and compare widths. You will see a free proof before anything is made, and you can ask for changes then.
