Two of the most practical questions when choosing a domain are how long it should be and whether hyphens are okay. Both directly affect how easily people can remember, type, and share your address — and both have clear best-practice answers. Get them right and your domain works smoothly for you; get them wrong and you quietly leak traffic to typos and forgetful visitors. This guide covers exactly what to do.

You will learn the ideal domain length and why shorter is better, the technical limits, how to test memorability, the truth about hyphens (allowed but best avoided), when a hyphen might be unavoidable, and how numbers fit in. By the end you will be able to judge any candidate name on length and punctuation with confidence.

The ideal domain length

The best-practice length for a domain name is roughly 7 to 15 characters, with many experts aiming for the 6 to 14 range. Within that window a name is short enough to remember, type quickly, and fit neatly on branding, while still having room to be distinctive. Shorter is generally better, right up until the name becomes cryptic.

The reason short wins is simple: every extra character is another chance to forget, mistype, or truncate the name. Names over about 15 characters are noticeably harder to recall and type, and long strings can start to look spammy or unprofessional. A concise name is easier to say, share by word of mouth, and reproduce correctly.

So aim short. Two to three words, or a single distinctive word, usually lands in the ideal range. If your candidate is drifting past fifteen characters, look for a tighter version — a shorter synonym, a coined word, or dropping a filler word — before committing.

Why shorter names win

Short names deliver a stack of practical advantages. They are easier to remember, so people can return by typing your address directly. They are faster and less error-prone to type, reducing the traffic you lose to mistakes. And they look cleaner everywhere they appear — in logos, on business cards, in ads, and in someone’s mouth when they recommend you.

Length also interacts with the radio test: a short name is far easier to say aloud and have someone spell correctly than a long, multi-word phrase. Every word you add is another word a listener has to catch and reproduce. Brevity is what makes a name “sticky” and shareable.

There is no meaningful upside to a long domain — length does not help SEO or credibility, and it hurts memorability. So treat shortness as a genuine feature to optimise for, trimming your candidates toward the tightest version that still reads as a real, distinctive name.

Technical length limits

Separate from best practice, there are technical limits worth knowing. Each label in a domain (the part between dots, such as the name before .com) can be up to 63 characters, and a full domain name can be up to 253 characters in total. So the system allows very long names — far longer than you should ever use.

These limits are effectively irrelevant to good naming, because a name anywhere near them would be a usability disaster. They exist for technical completeness, not as a target. The practical ceiling is the roughly 15-character guideline, well below the technical maximum.

So while you technically could register a 40-character domain, you never should. Knowing the limits mainly reassures you that a sensible short name is nowhere near any boundary — the constraint that matters is human memory, not the DNS spec.

Test your name’s memorability

A quick way to judge whether a name is the right length and clarity is to test it on real people. The classic is the radio test: say the domain aloud once and ask someone to write it down. If they spell it correctly without seeing it, the name is short and clear enough; if they hesitate or get it wrong, it is too long, ambiguous, or awkward.

You can also test recall: mention the name, chat about something else for a minute, then ask the person to repeat it. A good domain sticks; a poor one evaporates. These simple checks catch problems that are invisible when you are staring at the name yourself and already know it.

Testing is worth the two minutes because you are too close to your own idea to judge it objectively. If friends can hear your domain once and reproduce it, real visitors will too — and that is the whole point of getting the length and clarity right.

The truth about hyphens

Hyphens in domain names are technically allowed but should generally be avoided. They reduce memorability, make the name harder to communicate verbally (you have to say “hyphen” or “dash” in the middle), and are strongly associated with spammy or low-quality sites because they were heavily used to grab keyword variations of taken names.

The practical problems are real: people forget the hyphen or put it in the wrong place, so they land on the non-hyphenated version instead — which is often a competitor. A hyphenated name also looks less clean and professional, and it complicates every verbal mention of your address. None of this helps your brand.

There are technical rules too (hyphens cannot start or end a label, and you cannot use consecutive hyphens in certain positions), but the main point is simpler: even where allowed, hyphens are a best-practice no. If a hyphen is the only way to get a name, that is usually a sign to choose a different name.

How length and hyphens affect word of mouth

It is worth appreciating why length and hyphens matter so much: most of a site’s easy, free traffic comes from people remembering the name and sharing it out loud or in a message. A short, clean, all-letters name survives that journey intact — someone hears it, remembers it, types it, and arrives. Every extra character, hyphen, or number is a point where that chain can break.

Picture someone recommending your site in conversation. A tight name like “mapleforge.com” is repeated and typed correctly with no effort. A long, hyphenated one like “the-best-maple-furniture-store.com” forces them to specify the dashes and the exact wording, and the listener will likely get it slightly wrong and never reach you. The name itself is leaking your word-of-mouth growth.

So length and hyphen decisions are really decisions about how much of your organic, shared traffic actually lands. Optimising for a short, clean, sayable name is not cosmetic — it directly protects the cheapest and most valuable traffic you will ever get.

When a hyphen might be unavoidable — and numbers

Occasionally a hyphen seems necessary — for readability when two words would otherwise mash confusingly together, or because the non-hyphenated version is taken. Even then, weigh it carefully: the confusion and traffic leakage usually outweigh the benefit, and a different name is often the better answer. If you must use one, keep it to a single hyphen and try to also secure the non-hyphenated version and redirect it.

Numbers raise the same issues as hyphens. They fail the radio test (“5” versus “five”), invite typos, and can look unprofessional, so they too are best avoided unless a number is core to an established brand. As with hyphens, if you use a number, consider registering both the digit and spelled-out versions and redirecting one to the other.

The overarching best practice is a clean, short, all-letters name with no hyphens or numbers. That is the format people remember and type correctly, and it is worth reworking a candidate to achieve rather than settling for punctuation that quietly costs you visitors.

Frequently Asked Questions

How long should a domain name be?

Aim for roughly 7 to 15 characters (many target 6 to 14), or two to three words. Within that range a name is easy to remember, type, and fit on branding. Names over about 15 characters are harder to recall and can look spammy. Shorter is generally better, until the name becomes cryptic.

What is the maximum length of a domain name?

Technically, each label (the part between dots) can be up to 63 characters, and a full domain up to 253 characters. But these limits are far beyond what you should use — a name anywhere near them would be a usability disaster. The practical ceiling is the roughly 15-character best-practice guideline.

Are hyphens okay in a domain name?

They are technically allowed but best avoided. Hyphens reduce memorability, are awkward to say aloud (you must specify “dash”), invite typos that send people to the non-hyphenated version, and are associated with spammy sites. If a hyphen is the only way to get a name, it is usually better to choose a different name.

Why should I avoid hyphens in my domain?

Because people forget them or misplace them and land on the wrong (often competitor’s) site, they make verbal sharing harder, and they look less professional and more spammy. The traffic and trust you lose typically outweigh any readability benefit, so a clean, hyphen-free name is the best-practice choice.

Can I use numbers in a domain name?

You can, but it is best avoided unless a number is core to an established brand. Numbers fail the radio test (“5” vs “five”), invite typos, and can look unprofessional. If you use one, consider registering both the digit and spelled-out versions and redirecting one to the other to avoid losing traffic.

How do I know if my domain name is too long?

Use the radio test: say it aloud once and see if someone can spell it correctly without seeing it. If they hesitate or get it wrong, it is too long or ambiguous. As a rule, if it is over about 15 characters or more than three words, look for a shorter, tighter version.

The bottom line

For length, the best practice is short: aim for roughly 7 to 15 characters (or two to three words), because short names are easier to remember, type, say, and share, while long ones leak traffic to typos and look less professional. The technical limits (63 characters per label) are far beyond anything you should use — human memory, not the DNS spec, is the real constraint. Test candidates with the radio test to confirm they are tight and clear.

For hyphens, the answer is simple: avoid them. They are allowed but hurt memorability, complicate verbal sharing, invite typos to the non-hyphenated version, and look spammy. Numbers cause the same problems and are best avoided too, unless core to an established brand. Aim for a clean, short, all-letters name with no hyphens or numbers — that is the format people reliably remember and type correctly.
