A judge will lift anonymity orders protecting the identities of Brianna Ghey's killers next year.
The 16-year-old, who was transgender, was stabbed 28 times in a "ferocious" attack in a park in Cheshire.
Two teenagers, both now aged 16, were found guilty of her murder on Wednesday following an 18-day trial.
Trial judge Mrs Justice Yip said they could be named when the sentencing hearing takes place on 2 February at Manchester Crown Court.
Lawyers for the two teenagers opposed the media application to lift the restrictions, citing the possible ramifications on their welfare.
They also raised concerns over the consequences for their families, including death threats received by girl Y's family.
But Mrs Justice Yip said there was "a strong public interest in the full and unrestricted reporting of what is plainly an exceptional case", adding it was a "shocking event".
She accepted naming the two teenagers would "cause distress to their families" but the purpose of the order was not to protect family members of those convicted.
"I believe the appropriate balance can be achieved by directing that the order may be lifted but placing a [delay] upon it until the date of sentencing," she said.
Warning: Some readers might find the following report distressing
During the trial, the media was prohibited from publishing any details that would identify the two teenagers, who were referred to as girl X and boy Y.
The court heard the pair were intelligent, "high functioning" and came from normal backgrounds, but had a "thirst for killing" and a fascination with violence and torture.
The pair, who were 15 at the time of the killing, planned the murder for weeks before killing Brianna in Culcheth Linear Park in Warrington on the afternoon of 11 February.
A handwritten "murder plan" of how to carry out the killing was found in girl X's bedroom following her arrest.
The pair also drew up a "kill list" of five children, before settling on Brianna as their target.
On the day of her death, Brianna was lured to the park by girl X before being attacked with a hunting knife in broad daylight, suffering stab wounds to her head, neck, chest and back.
The pair had planned to conceal her body in the park but were spotted by a couple walking their dogs and fled the scene.
Her killers both tried to blame each other for the stabbing but were both found guilty of murder by a jury after four hours and 40 mins of deliberations.
Following the verdict, Brianna's mother Esther said the pair had not shown "an ounce of remorse" and she had "lost all sympathy" for them.
"To know how scared my usually fearless child must have been when she was alone in that park with someone that she called her friend will haunt me forever," she said outside the courthouse.
Her father Peter Spooner said: "My heart bleeds every day for Brianna, and this will never go away - and the amount of guilt I have can sometimes be unbearable.
"But I will ensure her memory lives on in my thoughts and dreams."
