Is a 4x9 LED sign the right size?
Built for monument and pole-mounted signs on 35–45 mph roads.
A 4x9 measures 4.2 ft tall by 9.5 ft wide — 39.7 sq ft of display per side, from a 4 × 9 grid of 12.6″ modules. It carries about 3 lines of comfortable text at roughly 13-inch character height.
At that character height the message reads clearly from about 390 feet, using the rule of roughly 30 feet of readable distance per inch of character. Measure from the road to where the sign will stand, and check that number against your speed limit before you commit to a size.
Common buyers at this size: car washes, churches, schools, restaurants and fuel stations. Compare it against the nearby sizes below — a foot in either direction moves the price more than most people expect.

Resolution
For a 4x9, we recommend Spotlight P8.
Pitch is how tightly the LEDs are packed. On a face this size it changes how smooth the edges of letters and logos look up close — not what you can put on the sign. P8 is sharp enough for a logo or a photo at a normal roadside setback, and during the Jumpstart event all three series cost the same. Full explanation in the buyer's guide →
Recommended · Spotlight P8
160 × 360 px per side
8,500 nits. The balance most 4x9 LED sign buyers land on — sharp for logos and photos at 64–80 ft.
Further than about 80 ft, or high on a pylon — choose Lighthouse P10.
Closer than about 50 ft, walk-up or drive-thru — choose Beacon P6 HD.
Pixel specs for all three series
Lighthouse · P10
128 × 288 px per side
Up to 10,000 nits. Best when the sign sits 80–100 ft or more from traffic, or high on a pylon.
Spotlight · P8
160 × 360 px per side
8,500 nits. The balance most 4x9 LED sign buyers land on — sharp for logos and photos at 64–80 ft.
Beacon · P6 HD
192 × 432 px per side
7,000–8,500 nits. For sidewalks, drive-thrus and tight frontage where people read it from 48–60 ft.

“The new sign has already brought in more foot traffic than we expected. Being able to change the message from my phone in seconds is a game changer.”
Getting a 4x9 LED sign up
Ship it to you, or we handle the whole thing.
A 4x9 LED sign at 360 lbs per side is within reach of most local sign crews, which is why ship-direct is the cheaper route for this size.
Lowest cost
DIY / ship-direct
Freighted to your address with L brackets, spares and engineered drawings in the crate. Add a retrofit bracket kit or a full pole kit above. Production and shipping run 6–8 weeks.
Configure and order this 4x9 →
Hands off
Professional turnkey install
Site survey, permit package, foundation, crane, electrical coordination and commissioning on one invoice. 6–12 weeks including permitting; production starts once the permit clears.
Price a 4x9 LED sign — turnkey →
Not included on either route: permit fees, the electrical run and any service upgrade, and drawings stamped by a licensed engineer if your city requires them ($350). A 4x9 LED sign single-sided draws 31 A at 110V — have your electrician confirm the circuit before install day.
Permits
What your city asks for, and what we hand you.
Most zoning boards want the same five things. Below is a real submittal — yours is prepared from your address and your 4x9 build.
If they ask about brightness or how fast it changes
Both are set in software, so we configure a 4x9 to whatever the ordinance says. The automatic sensor holds a maximum night-time brightness, and hold time between messages, fade instead of flash, and no-motion rules are all settings — not hardware. Tell us the ordinance language and we set the sign to match before it ships. Call (866) 343-4011 and we will read it with you.
Built to stay outside
Weather is the easy part.
A 4x9 lives outdoors for years at a time, so the cabinet, the optics and the electronics are all specified for it — and every part of it is serviceable from the front.
IP65 all-aluminum cabinet
Edgeless, sealed and powder-coated. Aluminum instead of steel, so nothing in the frame has anything to rust.
Front-service modules
Every module and power supply comes out from the face with a hex key. No lift, no crane, and no taking the sign down to fix one square.
Readable in direct sun
Outdoor brightness runs 7,000–10,000 nits, and the automatic sensor dims it at night so it never glares at your neighbors.
Spares in the crate
A spare power supply and control card ship with the sign, along with engineered drawings for your permit package.
Backed by 5-year full parts coverage, then lifetime system support. Labor and shipping are billed separately — the warranty policy spells out what is covered.
Why LED Sign City
Manufacturer-direct, and built to be changed later.
We build the signs we sell, in the USA, with no middleman markup — and we design them so the one you buy today is still the right sign in five years.
Upgradable
Every component is interchangeable, so you can move to a tighter pixel pitch or newer modules without replacing the sign. Lifetime support includes 40% module trade-in credits.
Scalable
Cabinets are modular. Add sections later and the controller, software and mounting all carry over — you are extending the sign, not starting again.
Easy to run
Free remote software with no subscription. Type the message, pick when it runs, and send it from your desk or your phone.
Live support
Real people on the phone at (866) 343-4011, Mon–Fri 9 AM – 6 PM CST, plus a step-by-step troubleshooter and a full parts catalog.
5-year warranty
Full parts coverage for five years on every component we supply, then lifetime system support with 40% module trade-in credits. Labor and shipping are not included — see the warranty policy for the full terms.

Counts are for a 4x9 LED sign and are printed on the packing list. A spare power supply and control card ship with every sign.
Electrical
2 × 20 A circuits
Runs share a 20 A breaker whenever their combined load fits, so a 4x9 needs 2 per face — 4 for a double-sided build. Total draw is about 31 A at 110V, or 16 A at 220V, per face.
Wiring order
Brightness sensor on section A’s spare power port, antenna cable on A’s outer signal port, the breaker feed on any free power port, then chain signal from section to section.
Structural load
360 lbs
Per face, at about 10 lbs per module. Have your engineer confirm the existing structure before a retrofit.

Assembly
How a 4x9 goes together on site.
Nothing over 4 ft ships as one piece, so a 4x9 arrives as 3 pre-assembled sections. Everything inside a section is factory-torqued — these are the only steps the installer performs.
·
Unpacking
Keep the crate upright and never rest a section face-down on the LED modules. You supply a 13/14 mm ratcheting wrench and a drill / driver with a 17 mm socket.

M8 bolts at the seams
Two M8 bolts per module on every line where two sections meet — 16 M8 bolts on a 4x9. Open tunnels only ever meet open tunnels; the outside edges stay sealed.
2
X brackets
One X bracket wherever four cabinet corners meet along a seam, four M10 bolts each — 6 X brackets.
3
L brackets
One L bracket every two modules around the perimeter, two M10 bolts each — 12 L brackets. This is what your wall, pole or monument frame bolts to.
4
Power
Each section has two interchangeable power ports. A 3-pin feed lands on one, and where two sections share a breaker a jumper carries the run to the next. Section A keeps a port free for the brightness sensor.
5
Signal
Section A takes the antenna cable or the network drop on its outer signal port; the inner port chains straight to the next section, and on down the line.
