Publishing group Hachette Filipacchi unveiled a new look and bigger format for its teen magazine Sugar on Wednesday, reports Media Week.

The title has been re-sized from its handbag ratio to be bigger than "but not as large as Grazia", according to editor of Sugar, Annabel Brog.

The pages of the magazine have been restyled and the paper stock has been improved. However, it will retain its logo and body copy font.

"In this market you refresh all the time - you have to for teenagers as our audience changes more quickly than any other," said Brog.

She added, "Certain formats that seemed very modern a while ago aren't now."

Publisher of Sugar, Rita Lewis said that Sugar along with its online version Sugarscape was "the single most powerful teen media brand."

"We are extremely excited to have been able to invest in the title as we have, with media firsts and a fresh design; innovation will continue to be at the heart of what we do," added Lewis.

The redesigned magazine will hit the newsstands with its December issue.
