Because the way a business letter looks immediately gives the reader their first impression even before they read it. The quality of the paper, letterhead design, the margins, spacing and more all have something to say about the organization.
A weakness in any of these elements can detract from the effectiveness of the message, even though it is expertly written.
I have a long list of the elements of the formal business letter format below. There is also a sample picture with all the elements highlighted for easier reference.
Color: White is the standard and should usually be used. Light tints (gray, blue, green, etc) are also becoming popular.
Size: To me the Letter or A4 are the only acceptable sizes. There are other sizes but I don’t recommend it unless you are in the creative field or you are trying to capture attention for a sales letter.

Whatever layout you wish to use, it does not really matter. As for me, I prefer the full-blocked simply because it is easier to type on the computer.
Any special instruction such as “Personal,” “Please Forward,” or “Confidential,” goes on the left side of the envelope below the return address. Place an “attention line” directly below the company name on an envelope.
Confidential: Ms. Susan Johnson
Make sure the address on the envelope is written so that a postal worker can read it at a glance.
When both a street and a post office address are given, the postal service will deliver your letter to the address that appears directly above the zip code.
On the envelope address, type the names of foreign countries all in caps.
Spell out all numerical street names from one to ten.
127 Ninth Avenue, North
127 E. 15 Street
Five Park Avenue
One Wingren Plaza
Use a hyphen between street and residence numbers.
556 - 91 Street

Do not abbreviate the month or use nd, st, or th with the day numbers, like May 5th, 2011. Also, do not use a month’s number, like 6/23/11.
Both date orders listed below are appropriate; however, the latter is used mainly by the government, the military, and those outside the United States.
December 10, 2010
10 December 2010
Make sure a person’s name is spelled correctly. A recipient may decide to ignore a letter that was written by someone who cannot spell his/her name.
Do not use both the title and the degree of a person. For example, write either Howard Wyatt, D.D.S. or Dr. Howard Wyatt and not, Dr. Howard Wyatt, D.D.S.
Two or more men are addressed as Messrs., which means Misters. Do not use first names with this abbreviation.
Messrs. Smith, Wyatt, and Fury
Two or more women are addressed as Mesdames, Mmes., or Mses. Do not use first names with these abbreviations:
Mses. Farb, Lionel, and Gray
When addressing couples, give both appropriate titles:
Dr. and Mrs. Harold Wright
Mr. Harold Wright and Dr. Margaret Wright
Drs. Harold and Margaret Wright
Dr. Margaret Wright and Mr. Steven Jones
Mr. and Mrs. Harvey Adams-Quinn
Ms. Margaret Wright
Mr. Steven Jones
In selecting a title, always notice the way an individual identifies him or herself. For example, some who hold degrees do not use their titles while others do.
Some married women prefer Mrs.; others prefer Ms. If you do not know the title the woman prefers, use the standard Ms. or drop the title altogether:
Place the inside address at least two lines below the date.
Place a person’s title after his name unless it is unusually long, then go to the next line.
Ken Green, President
Ken Green
Vice President of International Operations
The comma before the abbreviations Jr. and Sr. is optional.
Michael Jordan, Jr.
Michael Jordan Sr.
Dear Amy: (personal friend or close business associate)
Dear Mrs. Rider:
Dear Miss Spears:
Dear Ms. Tyler: (use Ms. If you don’t know the marital status or the preference)
Dear Mr. Farnham:
Dear Dr. Doom:
Dear Sir Elton John:
If you don’t know the name of the individual, address it to the individual’s title in the company and then use dear Sir or Madam: Here is an example:
Head of Human Resource
ABC Company
123 Sesame Street
Dear Sir or Madam:
But please only use this if you really cannot find out the name of the person. Most companies will tell you who the person is. All it takes is a phone call. It is also quite easy to find this information on Linkin these days.
If you are addressing to an organization and not an individual, then use the following:
Ladies and Gentlemen:
And if you want to highlight the letter to an individual(s) in the organization, use the attention line as follows:
Attention: Miss J. Fonda, CEOand Mr. M.Jackson, CFO
Ladies and Gentlemen:
If you are addressing officials, it requires a more formal salutation. See Addressing Business Letters for Officials for more information.
Also see business letter salutation for more information.

Your official business title goes under your name. This is optional and depends on how serious you want to be. For example, a formal employment offer letter would require one.

Although this page is about business letter format and this site is about writing business letters, I think it is prudent to talk about other types of written business correspondence. This will include the fax, memos and e-mails. Knowing when to use each type of correspondence is just as (if not more) important as the content itself. For example, you don't send a memo to congratulate someone.
The fax cover page
Often, fax transmissions are received in a common area and then forwarded to the proper recipient. The fax cover page is used to route your communication to the correct person and to ensure all the pages are received.
Here is a sample of a fax cover page
Follow these guidelines when using the fax
The memo is short for memorandum. It is used for short reminders, quick announcements or concise pieces of information. When using the memo format, don't communicate something of vital importance. Use the business letter format instead. Memo tends to be given less attention than a business letter written on the company letterhead. Memos should not be used for communications to people outside the company.
There is no rule for the format of the memo. Pick one and make it a standard for your company. The vital information in a memo are the date, the recipient, the sender and the subject matter.
The following is an example:
Date:
To:
From:
