Frequently Asked Questions

Q. How do I decide what size of warning sign I need?

Your choice of the size of warning sign will depend on factors such as the location of the sign, viewing conditions (low light vs. adequate lighting, distractions around the sign, etc.), the amount of text and/or the number of symbols on the sign, and the safe viewing distance. Warning safety signs usually have these standard sizes - 7”x5”, 10”x7”, 14”x10”, and 20”x14” with a safe viewing distance of 8ft., 10ft., 20ft., and 30ft. respectively.

ANSI also provides guidance about the letter size on the warning safety sign as per the minimum safe viewing distance, where the letter height measurement is based on the height of the capital letter ‘H’ in the message. The height of the signal word is required to be at least 50% greater than the letter height of the majority of the sign legend. You may refer to the table below to understand the letter sizing requirements.

Minimum safe viewing distance (feet)	Minimum letter height of letter 'H' in the sign legend (points)	Minimum letter height of the signal word (inches)
8	32	0.48
10	40	0.60
20	80	1.20
30	120	1.80

Q. Can I create my own warning sign?

With our custom warning sign templates, you most certainly can. Available in a variety of shapes, sizes, materials, and formats, these templates let you add your text, select a symbol/pictogram, and modify the font style/size. We offer OSHA and ANSI-compliant custom warning sign templates as well as templates for your property and for floor signs. Spanish and bilingual warning signs are also available.

Q. Which material are your safety warning signs made of?

Our warning safety signs are available in a variety of materials and formats. While our rigid plastic warning signs make for the more economical options, our standard aluminum signs offer greater durability. We offer 3M engineer-grade aluminum warning signs as well that are reflective and promise great visibility even in the dark. Some of our warning signs are available in glow and fluorescent formats as well.

Q. Can warning signs be customized?

Yes, of course. Choose from our many custom warning sign templates available in OSHA and ANSI formats. You can add your text and select the symbol/pictograph you want on your warning sign. We also offer customizable warning sign templates for properties and adhesive sign templates for floors.

Q. Can glow projecting warning signs be used indoors?

They absolutely can be. Our customizable glow projecting warning sign is made of 40 mil thick aluminum with a Glo Brite photoluminescent film lamination on the face of the sign. The sign does not require electricity or battery but absorbs light (natural or artificial) during the day and emits it to glow in the dark, and is suitable for use both indoors and outdoors.

Q. Is it possible to modify in-stock warning signs?

You may modify some of our in-stock warning signs with the help of the custom option visible on the left side of the product page, just below the sign product images. You can add your text, change clipart where available, and modify the font used on the sign.

You may also change the language of the sign from English to Spanish by selecting the Spanish option given right next to the custom option on the product page.
