Start with the distance, not the screen
The right digital menu board size is not a matter of taste or budget. It falls out of one measurement: how far away the furthest customer is standing when they read it.
Go stand at the back of your queue at the busiest moment of the day and measure the distance to the wall. That number decides everything that follows: screen size, item count, and font size. Pick the screen first and you will end up with a board that looks fine on your laptop and is unreadable from the door.
The 10:1 legibility rule
The rule signage designers use: one inch of text height for every ten feet of viewing distance.
So if the back of your line is 20 feet from the board, your item names need to be about 2 inches tall on the screen. Prices can match; descriptions can go a little smaller; nothing important should go below the rule.
Work it the other way and you get your screen size. Two-inch text means roughly 12 to 14 readable lines on a 43-inch panel and 16 to 18 on a 55-inch. If your menu needs more lines than that, you do not need a bigger font, you need another panel or a shorter menu. Usually the second one.
Sizing table by venue
| Viewing distance | Recommended screen | Min text height | Items per panel |
|---|---|---|---|
| 8-12 ft (small cafe, counter) | 32-43 in | 1-1.2 in | 8-10 |
| 12-18 ft (takeaway, QSR counter) | 43-49 in | 1.5-2 in | 6-8 |
| 18-25 ft (large QSR, food hall) | 55 in per panel | 2-2.5 in | 5-7 |
| 25-40 ft (stadium, cafeteria) | 65 in+ or video wall | 3-4 in | 4-5 |
| Drive-thru lane | 43-55 in outdoor, 2500+ nits | 2.5-3 in | 5-6 |
Notice what happens as distance grows: the screen gets bigger and the menu gets shorter. That is not a compromise, it is the correct trade. A board nobody can read from the queue is not a menu, it is wall art.
How many screens do you need?
One panel per menu category is the pattern that works, up to three.
A single screen is right for a cafe with a tight menu: drinks on top, food below, one promo strip. Two screens split food and drinks and give each room to breathe. Three panels is the sweet spot for a QSR counter: mains, sides and drinks, combos, then a promo or LTO panel.
Beyond three, you are usually not adding clarity, you are adding places for prices to drift out of sync. That is a control problem rather than a screen problem, and it is worth reading our multi-screen sync guide before you add a fourth.
Portrait or landscape?
Landscape suits wide food menus with two or three columns and a photo zone. It is the default for QSR counters and it matches how most people expect a menu board to look.
Portrait suits tall lists: drinks, coffee, specials, and especially tap lists in bars and breweries. A portrait panel takes 8 to 10 lines cleanly and lets you add panels sideways as the list grows.
One warning: if you want portrait, buy a display warranted for portrait mounting. Many consumer TVs are not, because heat behaves differently when you rotate the panel. Our hardware guide covers what to check.
Mounting height and sightlines
Sizing is wasted if the board is in the wrong place.
Aim for the centre of the screen at 60 to 70 inches from the floor for close-range boards, higher for a long queue so heads do not block the bottom third. Then check the bottom third specifically, because that is the part that gets blocked, and it is where most people put their prices.
Avoid mounting directly opposite a window or under a spotlight. Even a 700-nit commercial panel loses to direct glare, and no amount of screen size fixes reflection.
Frequently asked questions
What is the best digital menu board size for a small restaurant?
For a counter where customers stand 8 to 15 feet away, a single 43-inch display handles 6 to 10 items comfortably. Below 32 inches you will be shrinking type past the point of legibility.
How do I calculate menu board font size?
Use one inch of text height per ten feet of viewing distance. Measure from the furthest point a customer reads the board, divide by ten, and that is your minimum height for item names in inches.
Is one large screen better than several smaller ones?
Several panels are usually better. They let you split categories cleanly, keep each panel uncluttered, and fail gracefully: if one screen dies you lose a third of the menu, not all of it.
What size screen does a drive-thru need?
43 to 55 inches, in an outdoor-rated enclosure at 2,500 nits or more, with text sized for 2.5 to 3 inches. Sunlight readability matters far more than raw size outdoors, as we cover in the drive-thru guide.
How many items should be on one menu board panel?
Six to eight for a typical counter. Customers read a board for roughly eight seconds, so more items do not mean more information, they mean less of it absorbed.
Measure first, then buy
Every bad menu board starts with a screen someone bought before measuring the room. Get the distance, apply the 10:1 rule, and the size, the panel count and the item count decide themselves.
Then build the layout on MenuPi free on one screen, and go read it from the back of the queue.
