Coat of Arms vs Family Crest: What's the Difference?

Ask a roomful of people to describe their family crest and you will hear about stags' heads, oak leaves, lions and rather a lot of tartan. Ask someone who works in heraldry the same question and the answer is much narrower: the crest is one small part of a coat of arms — the figure that sits on top of the helmet. The two terms are used as though they were interchangeable. They are not, and if you are commissioning anything from a signet ring to a carved house sign, the distinction matters more than you might expect.

The short answer

A coat of arms is the whole thing. A crest is one piece of it.

Think of a coat of arms as a complete ensemble: shield, helmet, crest, mantling, sometimes supporters and a motto. The crest is only the device perched on the helmet — the bit that would once have been modelled in leather and fixed above a knight's head at a tournament. Calling a shield a crest is a little like calling a roof a house. You will be understood, but anyone with an interest in the subject will wince.

The confusion is understandable. Most of us meet heraldry through a single image: a shield with something sitting on top and a name underneath. The whole picture gets one name. In practice, that picture is a coat of arms, and the crest is the small figure at its summit.

What actually makes up a coat of arms

Heralds call the full design an achievement. It can include:

• Shield (or escutcheon) — the central panel carrying the main design.
• Helmet — usually shown in profile, facing left or right according to tradition.
• Crest — the figure standing on the helmet: a stag's head, a hand holding a sword, a boar, a bird.
• Torse — the twisted band of two colours sitting between helmet and crest, often drawn as a wreath of cloth.
• Mantling — the draped cloth falling from the helmet, cut into leaf-like shapes.
• Supporters — the animals or figures either side of the shield, granted to peers, civic bodies and some corporate arms rather than to most individuals.
• Motto — a scroll, usually below the shield in English arms and above it in Scottish arms.

Set out in words, a design might read like this. A blue shield, a gold chevron across it, three silver roses. Above the shield, a helmet in profile. On the helmet, a twisted band of blue and gold, and rising from that band a crest of a stag's head. Beneath the shield, a scroll reading Steady. The stag's head is the crest. Shield, helmet, wreath, mantling, stag and scroll together are the coat of arms.

Why "family crest" is a misleading phrase

Here is the part that surprises people. In the British tradition, arms are granted to an individual, not to a surname. A grant made to a man in 1750 belongs to him and, subject to the rules of descent, to his descendants. It does not belong to everyone who happens to share his surname.

So two families called Harper with no common ancestor do not share arms. Each may have its own, or neither may have any at all. There is no such thing as "the Harper coat of arms".

The habit of talking about family crests comes partly from the nineteenth century, when printers sold decorative sheets showing a crest beneath a surname, and partly from the internet, where the same idea reappears on framed prints and mugs. Some of those designs are copied from genuine grants. Many are invented, or borrowed from a family with no connection to the buyer. If a seller cannot tell you where a design came from, treat it as decoration rather than ancestry.

Crest, badge and other near-misses

Two more terms are worth separating, because they turn up in the same conversations.

A badge is a device used on its own — on livery buttons, flags, buildings, uniforms — without helmet or shield. Retainers could wear a lord's badge; they could not wear his crest. This is why so many historic badges look simple and bold: they had to be recognisable across a crowded courtyard.

Corporate arms belong to bodies rather than people: towns, schools, regiments, livery companies, hospitals. Plenty were granted in the twentieth century, which is why so many feature an open book, a torch, a ship or a wall.

As for the crest on a football shirt or a school blazer, that is usually a badge or a logo, whatever the marketing says. Heraldic language is old and precise, and using it loosely is exactly how the confusion spreads.

What this means when you commission a piece

Before you order anything, decide which of these you are actually after.

• A decorative device. A crest on its own — carved, engraved or embroidered — works beautifully as ornament, with no claim to ancestry attached. Plenty of customers want exactly this, and there is nothing wrong with it.
• Arms you can rightfully bear. This means establishing descent from someone who was granted arms, or holding a grant yourself. That is a research job, not a design job.
• Something new and personal. Many craftspeople will design a device for a house, a boat or a family in heraldic style without presenting it as a grant of arms. Ask them to be honest about which it is.
• A faithful reproduction of known arms. Then you need the blazon — the written description — rather than a picture from a search engine.

The blazon is what makes a piece accurate. Artwork varies from artist to artist: one illuminator draws a lion sleek, another draws it snarling, and both are correct. The blazon does not vary. Azure, on a chevron or three roses argent fixes the colours and the arrangement, and any competent carver or engraver can work from it. Hand your maker the blazon, not a low-resolution image, and you will get something you can pass on.

A short checklist before you order

1. Write down exactly what you want on the piece: crest alone, shield alone, or the full achievement.
2. Ask the seller where the design comes from. A grant, a published armorial, or "we made it up"? Any answer is fine, as long as it is a truthful one.
3. Get the blazon in writing and keep it with the finished piece.
4. Settle the metals and colours early. Gold and silver are metals in heraldry, not just shades, and a gold that reads as yellow paint will look wrong for a century.
5. If you think you may be entitled to existing arms, or you want new ones granted, approach the relevant heraldic authority before spending money on artwork — the College of Arms for England, Wales and Northern Ireland, or the Court of the Lord Lyon for Scotland. They will tell you what is possible.

None of this is meant to take the pleasure out of it. A crest cut into oak is a fine thing whether it is a genuine heirloom or a design made for your own front door. The trick is knowing which one you have — and saying so.
