The 84-page title, called Ctrl+Alt+Shift, will be sold in branches of WHSmith, specialist retailers including the Tate Modern and on the charity's website.
The first issue has a cover price of £3.95 and an initial print run of 30,000 copies. The charity declined to say how much the magazine cost to produce, but did confirm that it plans to publish it twice a year.
Katrin Owusu, head of youth marketing and innovations at Christian Aid, said the charity believed young supporters were still interested in print magazines, despite the rise in the popularity of online campaigning.
"If it's a well-produced product and a limited edition, then in our experience it sells," she said.
Copies of the first issue will also be given away with the March issue of lifestyle magazine Dazed & Confused and in some universities.
