Kourtney Kardashian and Travis Barker look SMALL next to Khloe Kardashian and Tristan Thompson. So how tall are they?

Khloe Kardashian was seen posing with her older sister Kourtney Kardashian as well as her husband Travis Barker.

Also with the stars was Khloe’s ex, basketball player Tristan Thompson.

But the photo looked odd as Kourtney and Travis – both dressed in black – looked so much smaller than Tristan and Khloe.

Turns out Khloe and Tristan are just tall people. Basketball star Tristan stands at 6ft9in. And Khloe is an impressive 5ft10in.

Kourtney is 5ft1in. And Travis is 5ft9in.

They were posing inside Khloe’s house to celebrate Tatum’s first birthday. He is the second child of Khloe and Tristan who already have daughter True, five.

She can still hold him with one arm: Khloe was celebrating Tatum’s first birthday

It was a special post for Khloe. It was her first family portrait with both her children.

The Good American designer was seen with both her son Tatum, one, and daughter True, five, as they sat on the grass of her backyard while playing with toys while wearing her black Prada sunglasses.

The 39-year-old reality TV star was beaming with joy as she smiled alongside her kids during Tatum’s first birthday bash.

Former partner Thompson was at the party, he was not in the frame-worthy snapshot.

Khloe looked youthful in her plunging white summer dress that had straps over her shoulders, a small waistline and a full skirt as she added high heels.

Her glam was on target as she wore her blonde hair down and had on rose-toned makeup as she added black sunglasses and a diamond necklace.

Her cherry red long nails was the only color to her look.

Little True was darling in a white dress as she smiled from ear to ear as she wore her hair in curls with a braid up the center.

And Tatum was distracted as he looked off in the distance while mom out a hand on his waist. He wore a white T-shirt, beige slacks and white socks.

Tristan did pop up in another photo – when he was with Khloe as well as her pregnant sister Kourtney – who was in all black – and her new husband, drummer Travis Barker of Blink 182.

Tristan wore a white shirt with white shorts and sneakers and a silver chain.

Kourtney appeared to have no makeup on as he bra peeked from under her tank top. She had on Prada sunglasses.

Travis was very dressed down in a black T-shirt with a scary man’s face on it, adding ripped black jeans and leather shoes with narrow sunglasses.

He put his hand on Kourtney’s bump as she held onto a matcha drink.

Khloe was also seen smiling as she sat on a sofa next to Kourtney, whom she has had her ups and down with on their reality TV show The Kardashians.

Other images showed Khloe holding only Tatum alone while they stood by balloons.

Another shot saw Khloe with her mother Kris Jenner, who looked young in a blue denim dress with a Chanel purse worn crossbody style.

And Khloe took time out to pose with Kris’ boyfriend Corey Gamble.

Kim Kardashian’s eldest child, daughter North West, also made a cameo while in the kitchen.

The first time Khloe treated her followers to several images of Tatum was on his birthday Instagram post.

She was seen holding her boy in her arms as she smiled for the camera.

The Kocktails With Khloe star was beaming with pride as she wishes her little one a happy first birthday.

‘Happy birthday, my sweet son!’ the Good American designer began her post. ‘I am a firm believer in that God gives you what you need and I needed you. God knew my heart needed you.’

Kardashian and Thompson are no longer a couple and have not been for a while.

They split two years ago but continue to amicably co-parent both kids in Hidden Hills, California.

The beauty’s post was very sweet and gushy as she added that she needed his ‘sweet and precious Smile.’
