I have to comment on this. I dont know where these statistics came from but in my opinion when you design a logo you should not worry about any other aspects except how the design looks while your designing it.
1- Who determines something is too tall and wide? a logo is what it is it should not have restrictions in the beginning process. All can be adjusted later of course
2-anything can be converted to black and white with some adjusting. If this was an important factor while designing you might as well design it in black and white
3-what logo CAN be reproduced at .5" length and be readable? mine sure cant. who the hell comes up with this stuff? and where shall a .5" logo be used at?
4. design the logo without parameters and let it fall where it may. When you start placing restrictions on doing a logo most good designers would say go somewhere else. You CANNOT have rules on design it interferes with the creative process. Your not allowed to let it all flow
Who comes up with this stuff? college grads that were "taught" design?
Concerning op post this logo aint gonna get it. the fonts are are not chosen well and we got 3 different elements going on and the do not complement the other. Get rid of the big letters and the megaphone style designs. the logo on left side is kinda cool and could be worked with
Why do you assume any of what listed needs to be layed down as law BEFORE design work begins?
A general concept is always going to come first. I always sketch around a bit before polishing up a design and making it all work. But yes, a finished logo should be able to conform to all/most of what I listed.
If it's too tall or too long, how will it look when it needs to be utilized on somthing like a business card? If it doesn't read well when reduced in size, how will it be viewed from a distance?
Also, don't fool yourself, logos that are too busy and poorly designed are generally miserable when converted to B&W. Any logo should be able to be reduced to a single color and still read clearly for any simple applications, like stamps, imprints on boxes etc...
As for where these "statistics" came from...about 100 plus years of graphic design industry on planet earth.
Take a look around you and the logos of large companies:
FedEx
UPS
AT&T
Best Buy
Starbucks
McDonald's
Target
Shell
Bell
Home Depot
Subway
HP
GM
GE
Intel
Kodak
Mitsubishi
Ford Pfizer
Visa
Mastercard
Warner Bros.
Apple
Microsoft
Without question, they all follow all the guidelines I listed.
It's about simplicity, boldness, branding and overall good design.
You can and NEED to have rules on graphic design, otherwise everything would be off balance, unclear, full of tangents and utilize Comic Sans as a typeface.
Now if that's not the way you work, hey, cool by me. I don't think that's any reason to snub your nose at anyone that has a focused education on the subject or may be more learned that yourself on the detailed specifics of graphic design. I'm a firm believer that I can learn something from anyone. However, those educated folks tend to have an inner rage against the people that grab a copy of illustrator and call themselves a designer the next day, so I guess it all balances out in the end
