これは何についてのものですか？
Your face reads as diamond when your cheekbones are clearly the widest span across your face, with both your forehead and the span between your jaw corners narrower than the middle.
Diamond is the outline in the nine that narrows most clearly in both directions, and reading it correctly depends on two distinctions most guides run together, such as:
– the difference between the width of your chin and the span across your jaw corners
– the difference between cheekbone width and cheek fullness, which move independently
– how diamond differs from heart, which puts the widest span higher up
– where hair and beard volume actually reach, and where a pair of glasses cannot
その他多数！
Everything below rests on which of three widths wins, and on nothing you have to measure.
キーポイント：
01One observation makes this reading: your cheekbones win the width comparison, and both ends of your face are narrower than the middle.
02A pointed chin is not the test. Compare cheekbone width with the forehead and the span between the jaw corners; the width of the chin tip is a different observation.
03A beard reaches the lower face and a haircut reaches the upper face, so those two are the controls that can change the outline, while a pair of glasses sits across the middle and cannot widen either end.
04Nothing here treats prominent cheekbones as needing to be balanced away, and leaving the angle through the middle of your face exactly as it is is a fair choice.
自分の顔の形を知るのに、複雑な計測や科学的な道具は必要ありません。
This guide sets out four observations, marks the point at which each stops being reliable, and then builds the styling advice on your answers rather than on a category.
How to See Whether Your Face Reads as Diamond
一度設定すれば
均一な照明の下で鏡に正面を向き、顎を水平に保ち、表情をリラックスさせ、頭をまっすぐ伸ばして正面を向く。
Keep your expression neutral, because a smile lifts and broadens the cheeks and will exaggerate the width you are trying to judge.
Push your hair back off your forehead, since this reading needs your forehead to be narrower than your cheekbones and hair at the temples produces that result on any face.
4つの観察事項（順不同）
観察事項１
Do the cheekbones win, and do both ends lose?
眉毛の上の額、頬骨の一番広い部分、顎の角の間の幅を比較し、その3つを順位付けしてください。
A diamond reading needs the cheekbones clearly first and both the forehead and the jaw behind them, which is what makes this outline narrow at both ends rather than tapering in one direction.
観察事項２
Jaw corners, not the point of the chin
When you rank the lower face, use the straight span between the two corners at the back of your jaw, below and slightly forward of your ears.
A narrow pointed chin is a separate observation from a narrow jaw, and a man can have a tapered chin on a broad jaw, so ranking the chin instead of the corners is what sends readers into the wrong guide.
観察事項３
How clearly do the cheekbones lead?
Go back to the ranking and ask how large the lead is: whether the widest span across your middle is obviously the widest, or only narrowly ahead of your forehead and jaw.
A diamond reading has the middle clearly ahead. A fuller face can blur the comparison, and so can a beard at the jaw or hair at the temples, so if you cannot call it confidently, record it as uncertain and read the oval guide alongside this one rather than trying to work out what lies under the skin.
観察事項４
How long is the face overall?
Set the drop from your visible central hairline down to your chin against the widest span across your cheekbones.
Length does not decide this reading, and you are noting it because a long diamond outline and a compact one take different hair advice once you get to the styling sections.
Keep the four answers, because the styling notes below work from your ranking and your length rather than from a category.
正面からの眺めでは解決できないこと
The four observations describe an outline seen from the front, and that outline is the whole of what they describe.
Cheekbones that form the widest span from the front are not necessarily the most forward-projecting part of your profile. Width across and projection forward are different observations.
A diamond label does not determine where your temples sit in relation to the inner corners of your eyes, or establish your eye spacing, nose shape or ear placement. Observe those features separately if they matter to a styling choice.
Take a side view if you want one and describe it in its own words, because a barber does use the profile when deciding how far forward to bring hair at the temples.
ランドマークが見えないとき
Cheek fullness is the complication that belongs to this reading, because a full cheek and a wide cheekbone produce the same silhouette from a distance.
If you have gained or lost weight recently, look again in a few months, since a leaner face tends to show the outline more sharply and a fuller one softens it. This guide describes what you can see rather than what produced it.
If a beard covers your jaw, rank the bearded outline as one answer and record the jaw beneath as unknown, because a beard left wide at the sides can put the widest span of your face at the jaw and remove the diamond reading altogether.
Hair at the temples narrows the forehead you are ranking, and a receding hairline does the opposite by exposing more of the forehead, so mark the length uncertain if your hairline is unclear and rank the forehead by the breadth you can see above your eyebrows.
鏡ではなく写真を参考にする場合は、レンズを目の高さに揃えて正面から撮影し、可能な限り後ろから撮影し、2枚の写真を比較する際は同じ頭の位置を保つようにしてください。2023年に特定のスマートフォンとカメラを使用して、さまざまな距離から12人の被験者を撮影した研究では、最も近い距離から撮影した写真では、顔の中央部の比率が変化することがわかりました。何気なく撮った写真は分類の正確な証拠にはならないため、写真に写っているものは結果ではなく説明として捉えてください。
If one cheekbone sits higher or wider than the other, note which and carry on, because an asymmetry is worth mentioning to a barber and is not a reason to change the name.
Diamond and the Names Next to It
これらの名称は、統一された基準ではなく、理容や身だしなみに関する文献から来ているため、枠線は編集上の慣例であり、このサイトでは使用している慣例を明記しています。
Read whichever comparison matches what you found ambiguous, and read two guides rather than forcing a single answer.
ダイヤモンド対ハート
This is the comparison readers get wrong most often, because both readings can show a narrow chin and both can look angular.
ハートの顔 put the greatest width at the brow, so the widest span sits high on the face and the outline tapers in one direction only, while a diamond reading puts the greatest width in the middle with both ends narrower.
A pointed chin decides nothing here, because both readings commonly have one; the ranking of forehead against cheekbones is what separates the two.
ダイヤモンド対三角形
三角形の面 on this site put the greatest width at the jaw, which inverts the arrangement described here.
Be careful with borrowed advice, since some publications use triangle for a brow-widest outline, so translate any recommendation by the width the writer says is greatest rather than by the label.
ダイヤモンド vs オーバル
楕円形の面 also have the cheekbones slightly ahead, so this comparison turns on how large the lead is.
An oval reading has the forehead and jaw close behind the cheekbones and the outline curving gently, while a diamond reading has both ends reading as narrow and the middle reading as an angle.
ダイヤモンド対スクエア
スクエアフェイス hold all three widths level with an angular corner at the jaw.
Both readings can look angular, so use the ranking rather than the impression of sharpness: level widths belong there, a clear win for the middle belongs here.
ダイヤモンド vs ラウンド
丸い顔 are compact with curved jaw transitions and no width clearly in the lead.
Use the widths, the length and the corners together: a round reading is compact with curved jaw transitions and no width clearly in the lead, while a diamond reading has the cheekbones clearly ahead of both ends. Fullness can make the two look alike in a photograph, so judge from a mirror where you can.
ダイヤモンド対長方形
長方形の面 keep the three widths level down a clearly longer outline.
Both readings can be long, so if your widths are level rather than peaking in the middle, the rectangle notes will suit you better.
特徴が混在している場合
Prominent cheekbones on a face whose forehead and jaw are only slightly narrower is a common reading that sits between this guide and the oval one.
Describe what you saw: cheekbones clearly widest, forehead a little narrower, jaw corners narrower still, chin tapered, outline longer than compact.
Those five observations give a barber more to work with than one name, and no confidence percentage belongs to any of it.
何を着るか決める前に、何が欲しいか決めよう
まずこれを解決しよう
Decide whether you want the angle through the middle of your face left alone or softened, because prominent cheekbones are a feature many men want on show rather than a proportion to be corrected.
Most advice for this outline sets out to add width at both ends, and that aim is a preference rather than a requirement.
You can reduce the contrast, which means width at the forehead and temples above and visible weight at the chin and jaw below.
You can leave the contrast alone, which means hair kept close at the temples and a beard kept short, so the cheekbones stay the widest span in your outline.
Notice which end you actually mind, because a narrow forehead and a narrow jaw take completely different remedies and few readers want both.
Hair: Width at the Forehead, Height at the Crown
その haircuts collected for diamond faces mostly aim at the narrower upper face, and they do it in two different places that are worth naming separately.
Width at the temples and a little length falling at the forehead narrow the gap between your forehead and your cheekbones, while height at the crown lengthens the outline rather than adding width at the top, so a quiff or a pompadour does not address the ranking you read even though both are often recommended for it.
A brief for reducing the contrast sounds like this: leave weight and texture through the temples rather than taking the sides in tight, and let a little length sit forward at the front instead of sweeping everything back.
If you would rather keep the cheekbones as the widest span, the opposite brief is short sides taken close through the temples with the length kept on top.
次に、自分の髪が実際にどうなるかを確認してください。それが、これらのうちどれを残すかを決めるからです。
以下は規則というより傾向です。なぜなら、髪の密度、カールパターン、長さ、成長方向はそれぞれ独立して作用し、結果は個々の組み合わせによって決まるからです。細い髪や密度の低い髪は、高さや幅を保つためにカットが必要で、多くの場合、乾燥も必要になります。また、一日を通して形が崩れやすい傾向があります。密度の高い髪は一般的に形を保ちやすく、思ったよりも幅が広く見えないように、重さを落とす必要がある場合があります。カールした髪や縮れた髪は、少ない労力で幅を保つことができ、乾燥すると縮むため、濡れた状態ではなく乾いた状態で仕上がりの形を決めましょう。髪質に関わらず、生え際の成長方向によっては、前髪や分け目がうまくできない場合があります。
Ask how the cut behaves three mornings after a wash, and dry it yourself once before agreeing that it suits you.
Beard: Width Low Down If You Want It
A beard sits on the narrow lower end of this outline and changes that contour directly, and hair long enough to fall past the jaw frames the same area, so the beard styles collected for diamond faces are worth reading closely if the lower face is what you want to change.
Split it into four decisions: how long the chin is left, how full the sides are, where the cheek line runs, and where the neckline sits.
Fullness carried out to the sides of the jaw is what adds visible width low down, and a squarer line under the chin broadens the bottom of the outline rather than pointing it, which is the opposite of what a tapered chin beard does.
If you would rather not broaden the jaw, a beard kept short and even leaves the cheekbones leading, and a goatee or chin beard narrows the bottom further still. If your face is also long, note that length at the chin adds to the apparent length as well as to the weight, so treat chin length as its own decision.
Your present growth coverage decides all of it, because width at the sides of the jaw needs density along the jaw line that not every man has, so choose an outline that works with the coverage you have now.
A fade in a beard means a graduated transition with no visible step, which is separate from how long the chin is left, so ask for the two separately; set the neckline in the mirror with your barber rather than by a finger-width rule.
メガネ：フレームでできることとできないこと
フレームは頬骨に沿って、上端が眉毛のライン近くに来るように装着されるため、視線が顔の上半分に引きつけられます。顎よりかなり高い位置にあり、顔の下半分の幅は変わりませんが、視線が最初にどこに集まるかによって、顔全体の輪郭の見え方が変わります。
Frames add their outline around the eyes. Their width can also change how the upper and lower face look relative to each other, so compare frames on your face rather than assuming they will make your jaw appear wider.
If you want the emphasis higher up, a frame with visible weight along its top edge does that, and if you would rather draw less attention to the middle of your face, a lighter rim and a shallower depth read as quieter.
Fit is the separate question and the one that decides whether you keep wearing them: enough overall width that the arms are not pressing your temples, a bridge that rests on your nose without pinching or sliding, arms that reach your ears at a length that holds, and enough clearance that the rims are not resting on your cheeks when you smile, which is a real nuisance on a face with prominent cheekbones.
テンプルの内側に印字されている3つの数字は、レンズ幅、ブリッジ幅、テンプル長をミリメートル単位で表したものです。これらは顔のサイズではなくフレームの形状を表しており、リムやエンドピースの形状が異なるため、フレーム前面の全体の幅とは一致しません。そのため、これらの数字は試着したフレームを比較するための目安として使い、フィット感を保証するものではありません。処方箋やレンズに関する質問は眼鏡店にご相談ください。また、サングラスの保護等級は別途確認事項としてお考えください。
首輪：幅、先端の長さ、快適性
襟は顎の下に位置するため、顎を広げることはできませんが、適度な開き具合であれば、狭い下顔面の下に水平線を描く効果があり、それが目的であれば、その効果を求めるのが良いでしょう。
A long narrow point does the opposite by drawing the eye down to the point of your chin, so leave it out if you are trying to broaden the bottom of the outline.
Comfort and band height come before the shape, since a collar that grips will be undone by lunchtime, and the knot needs enough room for your own tie.
For casual shirts and knitwear, the occasion and the jacket over the shirt matter more than your outline does.
ダイヤモンドの顔の形に関するよくある質問
Q. How do I tell diamond from heart?
By which width is greatest. A heart reading has the brow widest and tapers in one direction down to the chin, while a diamond reading has the cheekbones widest with both ends narrower. A pointed chin appears in both, so it decides nothing; rank your forehead against your cheekbones and the answer follows.
Q. Does a pointed chin mean I have a diamond face?
No. The width of your chin and the span between your jaw corners are two different landmarks, and a tapered chin sits happily on a broad jaw. Rank the corners rather than the point, because a reading built on the chin alone will put you in the wrong guide.
Q. Do I need to balance my cheekbones?
Only if you want to. Prominent cheekbones are a feature plenty of men choose to keep on show, and leaving the angle through the middle of your face alone is a legitimate decision rather than a missed correction. If you do want less contrast, decide which end you mind, since the forehead and the jaw take different remedies.
Q. Can this reading change over time?
How it reads changes. A leaner face tends to show the outline more sharply and a fuller one softens it, so this reading can come and go with weight and with age. If your weight has shifted recently, look again in a few months, and treat what you see as the current appearance rather than as a settled fact about your face.
Q. Does very short hair suit this outline?
Yes, and short sides leave the cheekbones as the widest span in your outline, which is the effect if you want it. If you would rather add width at the top, keep some length and texture through the temples rather than taking the sides in close.
Q. Does facial hair help?
A beard sits on the narrow lower end of this outline and acts on it directly, which is what makes it the usual answer when broadening the jaw is the goal, and longer hair can frame the same area. Fullness carried out to the sides with a squarer line under the chin is what adds width there, and your present growth coverage along the jaw decides how much is available.
