The United Nations has said it estimates that 10.25 million Syrians, or half the country's population, will need humanitarian aid by the end of this year.
It also estimates that the cost of this aid will top $5 billion (£3.2bn) this year.
The announcement comes as the UN launches the largest fundraising appeal in its history.
UNICEF estimates that more than 1.6 million people have fled the war in Syria - equivalent to the entire populations of Birmingham and Glasgow combined.
The number of people thought to need aid in Syria is roughly equivalent to the populations of Scotland and Northern Ireland combined.
- Over 1.6 million people have fled Syria into neighbouring countries
- 814,395 of those are children
- Some 6.8 million people in Syria need of humanitarian aid
- More than 3 million of these are children
- 3.9 million children in urgent need of humanitarian assistance in total
The aid organisation UNICEF says its work in Syria is underfunded by 30% until the end of June, a situation that is not sustainable given that the refugee camps they operate in are growing daily.
Today, UNICEF is launching an appeal that will - if the target is met - provide funding for their work until the end of this year.
They also run schools and 'child-friendly spaces' where children can feel safe and be helped to deal with the psychological impacts of war.
Jordan has denied claims that it has refused entry to refugees fleeing the violence in Syria.
The UN will launch their biggest aid appeal for Syria tomorrow, as the scale of the refugee crisis continues to escalate.
Jordan is already swelling with Syrian refugees and is now having to turn away some families who are desperate to escape the war.
ITV News has been reporting from the Zaatari refugee camp, a place now home to more than 100,000 people.
Every day, more and more refugees arrive on the border, hoping to reach the camp, but some say that they are being sent back over the border.
From Jordan, ITV News Middle East Correspondent John Ray reports.
Suleiman, 5, has just moved into his new home in Zaatari refugee camp in Jordan after fleeing the violence across the border in Syria.
He and his family will live in this tent - one among some 25,000 in the camp - for the foreseeable future.
Suleiman told our producer that he know any children here, but he will play with the kids in the tents next to his family one.
Reem Ziad al Helo is one of the many children at Zaatari refufee camp being treated for wounds inflicted in the Syrian war.
Her right foot was badly injured when a shell hit her home in the village of Sahem Touma in Deraa province. Her aunt was killed and her mother sustained minor injuries.
She has been having weekly sessions with a physiotherapist from Handicap International since arriving at the camp in January, but is still not able to walk.
Reem says she is determined to play football again, and to walk to school without a wheelchair.
The United Nations will launch their biggest aid appeal for Syria tomorrow, as the scale of the refugee crisis continues to escalate.
All week ITV News has been reporting from Zaatari, one of the biggest refugee camps in the world that lies just five miles from the Syrian border in Jordan.
Last September, there were approximately 2,500 tents and trailers there but within three months it more than doubled in size.
The camp now holds 25,000 tents with some 120,000 refugees calling Zaatari home - half of them are children.
ITV News' Middle East Correspondent John Ray reports from inside the camp.
The Syrian twins that ITV News viewers have been getting to know through our special reports from Zaatari refugee camp in Jordan looked much healthier today than they did a few days ago.
Doctors at the Médecins Sans Frontières hospital in the camp say Iman and Ayat still suffer from occasional diarrhoea and vomiting and are underweight, but are making a recovery.
Their mother told our producer she is very happy to see her daughters getting better but she fears they might relapse once they are back in the tent where they live.
Conflict in Syria has forced millions of people to flee their homes, creating a humanitarian crisis in which food assistance is a top priority.
Currently, the World Food Programme (WFP) is aiming to feed 2.5 million people inside Syria every month, distributing food both in areas controlled by the government and by the opposition.
The WFP is also assisting more than 800,000 refugees who have fled to neighbouring countries.
In a series of special reports, ITV News Middle East Correspondent John Ray is focusing on the plight of 100,000 Syrians at the Zaatari refugee camp in Jordan, where the WFP also distributes aid. Watch John Ray's latest reports here.
