  • WHY SIZE REALLY MATTERS

    • ⚖️ Balance & proportion: Too large can overwhelm, too small can disappear.
    • 👀 Legibility & visibility: Size directly impacts how clearly your message reads.
    • 💰 Budget & install: Bigger signs require more materials, power, and mounting consideration.
    • 🎯 Overall impact: The right size makes your neon the perfect focal point.

  • HOW TO CHOOSE THE RIGHT SIGN FOR YOUR SPACE

    📏 Measure Your Wall

    • Use a tape measure for width & height.
    • Leave 10–20% margin around the sign for breathing room.
    • Create a masking-tape or paper outline to visualise scale.

    ⚖️ Balance & Proportion

    • Don’t crowd shelves, frames, or windows — give the neon room to shine.
    • Larger surfaces typically suit larger statement pieces.

    🔤 Text & Design Length

    • More characters = more space required.
    • Long phrases may need two lines or a wider layout.

    ↔️ Orientation

    • Horizontal: great for banners like “Welcome to …”.
    • Square: perfect for logos and short names.
    • Vertical: suited to narrow walls and stacked text.

    📸 Mockup Tip

    Ask for a digital mockup placed on your wall photo before ordering — it prevents costly mistakes.

  • SHAPE & FORM: WHY SHAPE MATTERS

    • Rectangle / Square — clearest for text, space-efficient.
    • Circle / Oval — soft, balanced, and decorative.
    • Custom outlines — unique, brandable; may require larger sizes for fine detail.

    ⚠️ Complex shapes with thin strokes can lose clarity at small scales — size up to preserve detail.

NEON SIGN SIZE GUIDE - FREQUENTLY ASKED QUESTIONS

Read these to help get the right fit for your space:

Collapsible content

What size neon works best in a living room?

For most living rooms, a 45–60 cm (18–24″) width looks balanced above a sofa or TV unit.
If you’re creating a true focal wall, ~90 cm (36″) delivers more presence without overwhelming the space.
Measure the wall and leave 10–20% margin around the sign so it can “breathe”.
If your design is tall (stacked text or a logo), consider sizing by height rather than width to maintain readability.

How do I measure my wall so I don’t order too small or too big?

Measure the total available width/height with a tape, then mark a rectangle on the wall using low-tack tape or paper.
Step back to typical viewing distance and check the balance with nearby frames, shelves and windows.
As a rule, aim for a sign that occupies 60–70% of the width of the area you want it to fill (e.g., above a sofa or console).

How big should the letters be for good readability at distance?

A reliable rule of thumb is: letter height (cm) ≈ viewing distance (m) ÷ 10.

Examples:

  • 2–3 m away → letters 5–6 cm tall
  • 5–10 m away → letters 10–15 cm tall
  • 10 m+ away → letters 15–25 cm tall

If you’re using a script font with thin strokes, size up slightly to keep letterforms clear.

How many letters fit into 90 cm (about 36″)?

It depends on the font and spacing, but 6–10 characters is typical for 90 cm in a flowing script.
Blocky, condensed fonts fit more; wide scripts fit fewer.
Multi-word phrases usually work best across two lines or at a wider size so ascenders/descenders don’t collide.

Should I choose my size by width or by height?

We always quote our neon signs by width first.
For logos, monograms or stacked layouts, choose by height to maintain legibility.
If in doubt, ask for a mockup on a photo of your wall before ordering.

What shapes/backings help readability?

A simple rectangular or contour-cut clear acrylic backing keeps the focus on the design.
Minimal backgrounds and tidy line spacing boost clarity.
If your logo has fine detail, increase the overall size or simplify thin strokes so they don’t visually “drop out” when viewed from across the room.

Which neon colours are most readable?

High-contrast colours against the wall work best.
On dark walls, bright tones (white, warm white, electric blue, neon pink) pop.
On light walls, choose stronger hues (hot pink, red, deep blue).
Limit palettes to 2–3 colours to avoid visual noise.
Pale pastels look beautiful but often need a larger size for the same legibility.

Will the sign be too bright at night? Can I dim it?

Yes—use your free remote dimmer to tailor brightness for evening use or photography.
Dimming also helps cameras avoid blown highlights and banding.
For bedrooms and home bars, most customers end up using 30–70% brightness day-to-day.

Can I install a sign without drilling?

For temporary installs (events, rentals, flower walls), hang from top holes using clear wire/chain or cable ties to a frame. For permanent walls, standoff mounts give the cleanest, safest result.
Always route the cable neatly and avoid pinching the LED flex.

Can I use a neon sign outdoors or in a shop window?

Yes, but specify outdoor-rated construction and plan for weather protection.
Go larger for street-side readability (120 cm+ is common for shopfronts).
If required, add waterproofing. This includes a waterproof power supply, and be mindful of reflections/glare from glass if the sign sits in a window.

How long should the cable be and how do I hide it?

Signs usually have a clear lead from the sign to the power supply, plus a mains lead to your socket.

If your socket is further away, request a longer lead or plan trunking/cord concealment.

You can choose cable exit (left/centre/right) to suit your layout—just ask before finalising the design.

What do you need for a logo or custom artwork?

Vector files (.AI, .EPS, .SVG) are ideal; high-res .PNG with a transparent background also works.

Very fine detail may need simplifying or upsizing to remain legible in LED neon.
