Grand Opening Posters: Sizes, Substrates, and Placement

Grand opening posters fail for one of two reasons: nobody can read them, or nobody walks past them. Both are solvable before you print. We have specified, produced, and installed ceremony graphics for decades, and the difference between a poster that works and one that curls into a tube by noon comes down to substrate choice, type sizing, and where the thing gets mounted.

This guide covers standard sizes, paper versus rigid board, indoor and outdoor durability, readable type by viewing distance, placement mapping, and quantity planning. For the words that go on them, see our grand opening template guide. For broadcast copy across channels, our grand opening announcement guide handles that.

Standard Grand Opening Poster Sizes

North American print shops stock a predictable set of sizes. Ordering off-list adds days and cost for no gain.

Size	Dimensions	Primary Use	Typical Viewing Distance
Small poster	11" x 17"	Interior walls, counters, community boards	3–6 ft
Medium poster	18" x 24"	Entry doors, easels, hallway runs	6–12 ft
Standard poster	22" x 28"	Sidewalk easels, lobby displays	10–15 ft
Large poster	24" x 36"	Window displays, main entrance	12–20 ft
Extra large	36" x 48"	Ceremony backdrops, parking approach	20–35 ft
Jumbo panel	48" x 96"	Construction fence, building wrap area	35–75 ft

 

Our default for a single-location retail opening is a mix: two 24" x 36" pieces at the entrance, four 18" x 24" on easels along the approach path, and a dozen 11" x 17" for interior and community board distribution.

Portrait orientation outperforms landscape for entry and easel placement, because it matches how people scan a doorway. Landscape wins only for backdrops and fence panels.

Paper vs. Foam Board vs. Rigid Substrates

Substrate is the decision most people get wrong. A gorgeous paper poster on an easel outside on a breezy March morning becomes trash by 10 a.m.

Substrate	Thickness / Weight	Outdoor Life	Rigidity	Relative Cost	Best Use
Poster paper, gloss	100 lb text	Indoor only	None	$	Interior walls, taped windows
Heavy poster stock	100 lb cover	1 day, sheltered	Low	$	Framed indoor, window backing
Foam board	3/16"	2–5 days dry	Moderate	$$	Indoor easels, short outdoor use
Gatorboard	1/2"	2–3 weeks	High	$$$	Repeat-use easel signs
Coroplast	4 mm fluted	3–6 months	Moderate	$$	Yard stakes, fence, outdoor easels
PVC / Sintra	3 mm or 6 mm	1–2 years	High	$$$	Permanent-feel displays
Aluminum composite	3 mm	5+ years	Very high	$$$$	Long-term exterior

 

Foam board is the most misused material in this category. It looks premium indoors and delaminates the moment it gets damp. If a poster will spend any time outdoors unsheltered, go coroplast or PVC.

The Humidity Trap

Foam board and mounted paper both warp with humidity swings, not just rain. A poster staged in an air-conditioned lobby overnight and moved to a 78-degree sidewalk at 8 a.m. will show a visible bow within an hour. Acclimate rigid pieces in the space where they will live, or specify PVC and stop worrying.

Lamination and Coatings

Matte laminate kills glare and is what we specify for anything under direct light or near glass. Gloss laminate saturates color but reflects badly in photos — and your ceremony will be photographed. UV-inhibiting laminate matters for anything outdoors longer than two weeks; without it, reds and magentas shift noticeably in about three weeks of sun.

Readable Type Sizing by Viewing Distance

This is where expertise shows. The working rule across signage practice: one inch of capital letter height per 10 feet of viewing distance for comfortable reading, and per 25 feet for maximum legibility at a glance.

Viewing Distance	Minimum Cap Height	Point Size (approx.)	Max Words on Poster
5 ft	0.5"	36 pt	40–60
10 ft	1"	72 pt	25–35
15 ft	1.5"	108 pt	15–20
25 ft	2.5"	180 pt	8–12
50 ft	5"	360 pt	5–7
75 ft	7.5"	540 pt	3–5
100 ft	10"	720 pt	2–3

 

Read that word-count column carefully. A 24" x 36" poster read from 20 feet holds about a dozen words. Not a paragraph. A dozen.

Hierarchy That Survives Distance

Build three tiers and nothing more:

•       Tier 1 — the news, at full cap height for the distance. "GRAND OPENING" or the business name.

•       Tier 2 — date and time, at roughly 50–60% of Tier 1.

•       Tier 3 — address, offer, and web, at roughly 30% of Tier 1.

Anything below 30% of your headline height is decoration, not communication. Cut it.

Type and Color Choices

Sans-serif faces with generous x-height read best at distance. Avoid condensed weights below 2" cap height; the counters close up and letters blur.

Contrast beats brand color. Dark type on white or a light brand tint holds up in every lighting condition. Light type on dark works indoors under controlled light and fails badly in direct sun. The U.S. Access Board publishes contrast and legibility guidance that we treat as a floor, not a ceiling, for public-facing display.

Where to Place Grand Opening Posters

Placement is a walking exercise, not a desk exercise. We map every venue by physically walking the approach from each direction a guest arrives.

The Approach Path Map

Work outward from the door:

1.    Door and entry glass — 24" x 36", eye level at 5'6" center. The last confirmation a guest needs.

2.    Storefront window — 24" x 36" or larger, positioned so it clears interior fixtures and parked cars.

3.    Sidewalk easel, 15–30 ft out — 22" x 28" on a weighted A-frame or easel.

4.    Corner or intersection — coroplast yard stake, readable at 50 ft, three to six words.

5.    Parking lot entrance — directional poster with an arrow, 24" x 36" minimum.

6.    Parking lot to door path — one directional every 75–100 ft if the walk is long or ambiguous.

7.    Ceremony area — 36" x 48" backdrop or step-and-repeat behind the ribbon line.

8.    Interior wayfinding — 11" x 17" at restrooms, registration, and the offer redemption point.

9.    Community boards off-site — 11" x 17" at libraries, coffee shops, gyms, chambers.

Position outdoor pieces at 90 degrees to the direction of travel, not parallel to the wall. A poster facing down the sidewalk gets read; a poster flat against the building gets passed.

Height and Sightlines

Center eye-level graphics at 5'4" to 5'8". For seated or drive-by viewing, drop to 4'0" center. Anything above 7 feet needs to be sized for the greater diagonal distance, and most people simply do not look up.

Check sightlines with people standing in the space. A poster perfectly placed at 7 a.m. disappears behind a crowd at 10:30.

Permits and Property Lines

Sidewalk A-frames, yard stakes in the right-of-way, and anything on a public pole usually require a municipal permit or violate sign code outright. Check with your city before you print. Landlord approval is separate from city approval, and shopping-center associations often have their own rules on window coverage percentage.

Quantity Planning

Under-ordering is more expensive than over-ordering, because reprints carry a rush fee and a second setup charge.

Venue Type	24"x36"	18"x24"	22"x28"	11"x17"	Coroplast Stakes
Single storefront, urban	2	4	2	12	4
Strip center unit	2	4	3	15	8
Standalone building with lot	3	6	4	20	12
Multi-tenant office or medical	2	8	3	30	4
Dealership or large lot	4	8	6	25	24
Civic or campus building	3	10	4	40	6

 

Add 15% overage on every size. Damage during transport and install runs about one in ten pieces on a typical job, and a spare 24" x 36" in the back room has saved more openings than we can count.

Order easels and stands with the posters, not separately. Weighted A-frames and 6-foot adjustable easels sell out locally the week of any large community event.

Lead Times

Digital poster printing on paper or foam board runs two to four business days. Coroplast and PVC run four to seven. Large-format laminated work adds two days. Rush service typically doubles cost for a 24-hour turn.

Build in a proofing day. We ask clients to print one 11" x 17" proof and tape it to the actual wall before committing to the full run. That single step catches contrast failures, sightline problems, and typos more reliably than any on-screen review.

Coordinate poster art with your grand opening banner, grand opening sign, and overall event signage so the site reads as one designed campaign rather than a collection of separate orders. Our ceremonial decorations and props collection covers the ribbon-line elements posters frame.

Common Mistakes to Avoid

Too many words. A 24" x 36" poster read from 20 feet holds about twelve words. Most drafts arrive with forty.

Foam board outdoors. It warps within hours in humidity and delaminates in any moisture. Use coroplast or PVC.

Type below the distance threshold. If the address is set at 24 pt on a poster read from 20 feet, nobody reads the address. Size to the table or cut the line.

Gloss laminate under direct light. Glare kills legibility and ruins event photography. Matte laminate outdoors and near windows.

Posters flat against the wall. Angle outdoor pieces 90 degrees to the direction of travel.

Skipping the physical proof. On-screen review misses contrast failures every time. Tape an 11" x 17" proof to the real wall.

No overage. Order 15% extra. Install damage is routine.

Ignoring sign code. Sidewalk placement and right-of-way stakes often require permits. A code violation on opening morning is an avoidable headache.

Forgetting the transition. "GRAND OPENING" posters need a replacement plan for day two. Order the "NOW OPEN" version in the same run.

The Practical Summary

Choose the size from the distance, choose the substrate from the weather, size the type from the table, and walk the approach path before you place anything. The design tradition behind large-format display work is well documented in Wikipedia's entry on posters, and the SBA covers the permitting and local-compliance side of storefront promotion. For the copy that fills these layouts, our grand opening invitations guide handles the printed guest-facing pieces.

Frequently Asked Questions

What size should grand opening posters be?

Match the size to viewing distance: 11" x 17" for interior and community boards, 18" x 24" for entry doors and easels, 24" x 36" for windows and main entrances, and 36" x 48" or larger for ceremony backdrops and parking approaches. A single storefront opening typically needs a mix of all four.

Should grand opening posters be printed on paper or foam board?

Use paper or heavy poster stock indoors only, foam board for indoor easels and brief sheltered outdoor use, and coroplast or PVC for anything genuinely exposed. Foam board warps in humidity within hours and delaminates in any moisture, which makes it the wrong choice for a sidewalk easel.

How large does the type need to be on a grand opening poster?

Allow one inch of capital letter height for every 10 feet of viewing distance for comfortable reading. A poster read from 25 feet needs roughly 2.5-inch caps on the headline and should carry no more than eight to twelve words total.

Where should grand opening posters be placed?

Work outward from the door: entry glass, storefront window, a sidewalk easel 15 to 30 feet out, a corner or intersection stake, the parking lot entrance, directional pieces along the walk, and the ceremony backdrop. Angle outdoor posters 90 degrees to the direction of travel rather than flat against the building.

How many grand opening posters should we order?

A single urban storefront typically needs two 24" x 36" pieces, four 18" x 24", two 22" x 28", twelve 11" x 17", and four coroplast stakes. Add 15 percent overage on every size, since roughly one in ten pieces gets damaged during transport or installation.

How long does it take to print grand opening posters?

Digital printing on paper or foam board runs two to four business days, while coroplast and PVC take four to seven, and large-format lamination adds two more. Build in an extra day to print a small physical proof and tape it to the actual wall before committing to the full run.
