From 29 January, the new look supplement will feature a larger 270x230mm format - it is currently 260x205mm - and the launch issue will be 84pp.
In a statement, Telegraph Media Group (TMG) said: "These weekend changes follow extensive reader research and reflect the needs and interests of our growing community of subscribers, as well as altered reading habits.”
As well as a number of new editorial elements, the new look supplement will include a "beautiful and useful Food & Drink pull-out".
A spokesperson said Prinovis in Liverpool, which has printed The Telegraph supplements since 2016, will continue to produce the title.
The relaunch is part of the group’s ambition to continue to build its subscriber base. The newspaper surpassed 720,000 subscribers across print and digital last year, and has set itself the ambitious target of 1 million subscribers in 2023.
TMG chief executive Nick Hugh said: “Reaching 720,000 subscriptions was a key ambition for 2021 and a testament to the excellent work of everyone at the Telegraph. I am delighted that we are making excellent progress towards our goal of 1 million subscriptions.
“Subscription figures are the key measure of our success, and across an industry which lacks subscription standardisation and transparency, TMG has led the way ensuring full transparency with independent, consistent monthly subscription reporting.”
In 2020, the title moved away from an ABC audited circulation to instead issue monthly subscriber numbers independently assured by PricewaterhouseCoopers.
