20 Triangle Tattoo Ideas So Stunning You’ll Pin Them All

ByTravis Costello

Whether you’re deep-diving for ink inspo or casually stalking your favorite celeb’s newest piece, triangle tattoos keep popping up — and for good reason. They’re simple but rich with meaning: they can nod to the Holy Trinity, suggest stability and balance, or just look beautifully geometric on your skin. I rounded up twenty ideas that I’m low-key obsessed with and thought you might like them too.

Tiny triangle on the side of your arm

Starting things off with a classic: a clean linework triangle on the side of the arm. It’s so simple and straightforward that it’s hard to go wrong. Whether you love triangles for the symbolism or just because you like geometric vibes, this kind of small, neat piece is a really reliable choice.

Dotwork triangles are so dreamy. They’re built from tiny dots that come together to form a soft, almost airbrushed look — delicate but detailed. If you want something gentle that still has texture and presence, this style is a lovely pick.

You can play around with two, three, or a whole stack of triangles in different sizes and orientations. Work with your artist to mix shapes and spacing — the result can feel balanced and elegant or chaotic and bold, depending on what you want.

Triangles with a sword (for extra meaning)

If you want to shift the message, add another element like a sword. It changes the vibe — now the triangle isn’t just geometry, it’s about protection, strength, maybe even honor. Same goes for flowers or other shapes: they can completely transform the story your tattoo tells.

Triangles don’t have to be plain. Slip in a number — a birthday, anniversary, or some secret code that means something to you. It’s an easy way to personalize a geometric piece and give people something to ask about.

Penrose triangles are the deliciously impossible ones — those optical illusion shapes that bend your brain a little. A broken Penrose triangle reads like a paradox: mysterious, clever, and kind of rebellious. Great if you like a brain-teaser as body art.

This one feels whimsical — triangles interacting across the curvature of the back, all in dotwork. There’s something almost celestial about it, like constellations that follow your body’s natural lines. Totally recommend if you want something that moves with you.

Floral triangle on the forearm

Can’t escape floral tattoos — and you don’t have to. Fill a triangle with blooms, tuck flowers into the negative space, or pick your birth month flower. It’s feminine, meaningful, and gives a soft counterpoint to the triangle’s geometry.
