Your windows are prime advertising space. People walking past look at them, and people driving past see them at eye level. Window decals turn that glass into a sign, a menu, a privacy screen or a seasonal display, often for less than any other sign.
Gogi Signs designs and installs window decals for businesses across New Jersey and New York City. Here are ten ways they help, with the limits and specs to know first.
In a 2026 Harris Poll survey commissioned by Signarama, a sign franchise, 46 percent said window graphics or displays catch their attention, and window graphics ranked second only to the storefront sign as the format most likely to make people want to walk inside, according to Signarama.

Window Decal Types at a Glance
1. Brand the Storefront
Your logo and name on the glass, at eye level, confirm people found the right place. This works well on a second floor or a narrow storefront where a big sign does not fit. Gold leaf lettering gives a classic look. See our gold leaf decals.
2. Post Hours and Contact Details
Hours, phone and website on the door answer the most common questions, even when you are closed. Use simple cut vinyl so they are easy to update.
3. Show What the Business Does
A short list of services or products tells people walking by whether to come in. Keep it to a few words per line.
4. Run Seasonal Promotions
Printed decals can change with the season or the sale. Removable films come off cleanly, so you can switch them often. Check your town’s rules on temporary window signs, since some allow more coverage for short periods.
5. Add Privacy Without Blocking Light
Frosted film hides offices, treatment rooms or storage while keeping the light. It can include your logo cut out of the frost. See our window frosting.
6. Mark Glass Doors and Walls
A band of frosted dots or a logo at eye level makes large glass easier to see. We could not find a New Jersey or NYC rule that requires these markings on ordinary storefront glass, but they are a common safety courtesy.
7. Turn the Window Into a Display
Perforated window film lets you cover the whole window with a printed graphic while people inside can still see out. Avery Dennison’s MPI 7000 perforated film has 40 percent open area and lets the full graphic be seen from one side while still allowing a view through the window, on its data sheet. Some towns count it toward window limits, so check first.
8. Highlight Payment and Delivery Options
Small decals for accepted cards, delivery apps and online ordering help people decide before they walk in. Keep them grouped near the door so they do not clutter the glass.
9. Share Credentials and Ratings
Licenses, awards, memberships and review ratings build trust. Our sister company in New York covers more types in different types of window decals.
10. Direct People to the Right Door
Entrance, exit, deliveries and upstairs offices all benefit from a clear decal on the right door. Pixel Wraps, our sister graphics shop, explains when simple lettering beats full coverage in truck wraps vs vehicle lettering.
Postings Some Businesses Must Show
- New Jersey no smoking sign. Indoor public places and workplaces must post a no smoking sign at every public entrance, with letters or a symbol that contrast with the sign, under statute 26:3D 61.
- NYC refund policy. The city’s consumer agency tells shoppers that stores must post their refund policy near the register, and that services such as salons must post prices at the register, in its consumer guide.
Check the Rules Before Covering the Glass
A grand opening banner that stays up for a year fades and frays and tells customers you never finished opening. New Jersey towns also limit how long banners stay up. Middlesex Borough allows a grand opening banner for up to 30 days, Glen Rock for up to three weeks, Flemington for up to 14 days and Plainsboro for up to 10 days a year. The fix: set the take down date when the banner goes up. Our guide to temporary sign rules covers more towns.
9. Ignoring Maintenance
- Montclair. Up to 20 percent of each window, according to its signage page.
- Hoboken. Up to 30 percent for permanent window signs and 50 percent for temporary signs, under section 196 31D of its code.
- Linden. Up to 25 percent of any window, under section 31 25.3 of the city’s zoning code.
- NYC historic districts. Vinyl can cover no more than 20 percent of each window, according to the Landmarks guidebook.
How Long Window Decals Last
ORAFOL rates its ORACAL 651 vinyl, which it lists for window graphics, for up to 6 years on vertical surfaces in its mildest climate zone, on its data sheet. Perforated films have shorter ratings, 2 to 3 years for Avery’s MPI 7000 series in European conditions. Sun facing windows fade faster. Our guide to outdoor sign materials covers vinyl grades in more detail.
Installation and Care
- Clean glass before install, with no residue.
- Inside or outside. Inside mounting protects the decal from weather and scraping. Outside mounting reads better through tinted glass.
- Gentle cleaning. Soft cloth, mild soap, no scrapers near the edges.
- Professional removal with gentle heat when it is time to change.
See our graphics installation service.
Design Tips for Window Decals
- Keep the main message at eye level, where people walking by look.
- Use contrast. White or light decals read best on dark glass, and dark decals on bright interiors.
- Leave clear space. People want to see inside, and many towns cap coverage anyway.
- Match your brand. Use the same logo, colors and fonts as your main sign.
What Affects the Cost
Price depends on the size, the number of colors, cut vinyl vs printed film, perforated or frosted film, and how many windows you cover. Simple cut vinyl hours and logos cost little. Full window graphics and gold leaf cost more. Every Gogi price includes design, production and installation.
Common Questions About Window Decals
How much of my window can I cover in NJ?
It depends on the town. Montclair allows 20 percent of each window, Linden 25 percent and Hoboken 30 percent for permanent signs.
Can people see out through perforated window film?
Yes. Perforated film has small holes, often 40 percent open area, so the graphic shows outside while people inside can still see out.
How long do window decals last?
It depends on the film. ORACAL 651 is rated up to 6 years on vertical surfaces, while perforated films are rated for less. Sun facing windows fade faster.
Do glass doors need decals?
We found no New Jersey or NYC rule that requires them on ordinary storefront glass, but a band at eye level is a common safety courtesy.
What signs must be on my door in New Jersey?
Indoor public places and workplaces must post a no smoking sign at every public entrance. Other postings depend on your type of business.
Can window decals be removed?
Yes. Most come off with gentle heat. Removable films are made for short term promotions.
