ST Kids will have a print run of 300,000 twice a year. Printed by Polestar, with colour reproduction by Colour Systems, the A4 glossy title will have 52 pages of content on everything from kids' fashion to books and lifestyle, and will be edited by Peter Howarth.
It will be distributed in London and to Telegraph readers in the South East.
Telegraph Media Group director of magazine sales Carley Ayres said: "The launch of ST Kids marks an exciting move into the parenting sector for TMG.
"We saw a significant gap in the market for a magazine which focuses on older children, which would benefit both our readers and commercial partners."
Other magazines in the range include ST Fashion, ST Men's Style and ST Design and Interiors.
