Calum Hood’s tattoos have grown along with 5 Seconds of Summer. Some are tiny and easy to miss, while others are big enough to catch your eye the second he takes his shirt off on stage. The fun part is that a lot of the ink has a clear story behind it. There are family initials, an important band year, a tribute to his sister, a tattoo picked up after getting stranded in Bali and a few designs that simply looked cool at the time.
Hood has never treated his body art like one perfectly planned sleeve. It feels more like a scrapbook that kept getting new pages as the band moved from small rooms in Sydney to arenas around the world. That gives the collection a relaxed, lived-in feel. Some pieces mark people, some mark places and some are reminders of the strange, funny moments that happen when four young musicians spend years travelling together.
This is a look at the best-documented Calum Hood tattoos, with the focus kept on designs that have been shown or explained rather than guesses based on a blurry concert photo.
MMXII marks the year everything changed
One of Hood’s earliest and most recognisable tattoos is MMXII, Roman numerals for 2012. That was the year 5 Seconds of Summer started to feel real. The band had formed the year before, but 2012 brought the early momentum that changed the members’ lives. The number is a quiet way of carrying that turning point around with him.
It is also a very Calum kind of tattoo. It is not a giant logo or a dramatic quote. It is a short date that only really makes sense if you know the person wearing it. Fans can read it as a band reference, while Hood can look at it and remember the nervous early days before the touring, records and huge crowds became normal.
The bird and Mali-Koa tribute keep family close
Hood has a bird design connected with his older sister, Mali-Koa. The name sits with the image, turning what could have been a simple bird tattoo into something much more personal. He has spoken about his family in interviews, and this piece is one of the clearest examples of that connection showing up in his ink.
There is nothing overly polished about the idea. It is basically a family name placed beside an image that suggests movement, freedom and travel. That combination suits Hood, whose work has kept him on planes and tour buses for most of his adult life. The tattoo still points back to home, even when he is performing on the other side of the world.
His parents’ initials are tucked into the details
Several of Hood’s smaller tattoos honour his parents through initials. They are the sort of details that can disappear when he is wearing jewellery or playing bass, but close-up photographs show how much of the collection is built around family. The initials are personal without being loud, which seems to be the point.
These little marks also balance the bigger, more decorative pieces. A feather or a horseshoe might be chosen for the shape, but initials carry a direct message. They say who mattered before the band became a public story. That is why the smaller tattoos are worth paying attention to; they give the rest of the collection a centre.
ALIVE and the 5SOS mark bring the music into the picture
Hood also has the word ALIVE and a design associated with 5SOS. The lettering is simple, but it lands well on a musician who has spent years turning restless energy into songs and live shows. It reads like a small reminder to stay present rather than a slogan designed for a motivational poster.
The band reference works in a similar way to the MMXII tattoo. It ties his body art to the group without covering him in a huge piece of obvious branding. 5 Seconds of Summer is a major part of his life, but the ink still feels like something a person chose for himself, not merchandise printed on skin.
The Bali tattoo came from being left behind
One of the best stories in Hood’s tattoo collection comes from a trip to Bali. He forgot his passport and ended up staying on the island after the rest of the band had moved on. His friend Roy English kept him company, and Hood got an R tattoo to remember the situation and the friendship.
It is a funny origin story, but it also explains why tattoos can feel like travel souvenirs for musicians. Hood was stuck in a place where he had not planned to spend extra time, and instead of treating the delay as a disaster, he turned it into a permanent memory. The later Bali Tour ’16 tattoo keeps that same chapter connected to the band’s touring life.
Feathers, a horseshoe and the Native American design
Photos of Hood’s arms and chest show a mix of feather imagery, a horseshoe and a larger Native American-inspired design. The feather is one of the cleaner, lighter pieces in the collection, while the horseshoe brings in a familiar luck symbol. Not every design has a detailed public explanation, so it is better to describe the visible work than pretend there is a hidden meaning nobody has confirmed.
That is part of what makes the collection easy to recognise. Hood mixes fine lines and heavier black shapes instead of forcing everything into one style. The tattoos do not need to match perfectly. They feel like pieces collected during different eras, with the earlier designs sitting alongside newer work as the musician’s taste changed.
The Used reference is a piece of music history
One tattoo is connected to the cover art for The Used album In Love and Death. That reference makes sense for Hood’s musical background. Before 5SOS became a global pop-rock band, he was a teenager absorbing the records and imagery that shaped his taste. Putting a favourite album reference on his skin is a pretty direct way of keeping that influence around.
It also shows that his tattoo choices are not only about biography. Some are tied to family or a specific year, while others come from the music he loved. That mixture stops the collection from becoming too neat. You get emotional pieces next to band memories and visual ideas that were simply important during a particular phase.
What the collection says about Calum Hood
Hood’s tattoos are personal without being overly serious. There are plenty of sentimental ideas here, but there is also room for a ridiculous travel story, a design chosen because it looked good and a tattoo that came from his friends teasing him. That balance fits the way he has talked about 5SOS over the years. The band’s history includes hard work, homesickness, inside jokes and a lot of time spent together in unfamiliar places.
The family tattoos give the collection its emotional base. MMXII and the 5SOS mark show how important the band’s early years were, while the Bali tattoo turns a travel problem into a good story. The feather, horseshoe and other images fill in the visual side. They are not all meant to explain his life in words. Some are there because he liked the shape or wanted a bit of fun on his skin.
There is no need to force the tattoos into one grand theme. The better way to read them is as a timeline. A young musician gets a date for the year his life changes. A family name and initials follow. A strange passport problem produces an R. Later, tour memories and musical references add more layers. The result is a body covered in reminders of people, songs, places and moments that would otherwise disappear into the blur of touring.
Hood’s ink also shows why small tattoos can carry just as much weight as large ones. The Roman numerals are modest, but they point to the start of a career that reshaped his life. The initials do not dominate a photograph, but they connect him to his parents. The Bali R might look like a random letter to anyone else, yet it holds an entire travel story. That is the good stuff in his collection: the meaning is there if you know the backstory.
As his solo work and 5SOS career keep moving, the collection could easily grow again. He has never seemed interested in making every tattoo part of one planned project. New music, new trips and new friendships all leave room for another small piece. For now, the existing tattoos already give a pretty clear picture of a bassist who carries his family, his band and his weirdest travel days with him.
