The new audit, which shows the magazine's average monthly circulation in the May-October period, was carried out by Emap's independent auditors Stephenson Smart & Co and was consistent with an Audit Bureau of Circulation audit.
The lastest circulation figure is up almost 7% on the January-June figure of 250,370, but still trails the market leader Sugar, now owned by Hachette UK following its £40m purchase of Attic Futura. Sugar's circulation for the January-June period was 346,449.
The revamp was supported by a £2m marketing push and, as well as a rise in readers, it has attracted new advertisers including Ralph Lauren, H&M, Benetton, Tammy and Billabong.
Rory Bett, director of youth magazines at Emap Advertising, said: "The response to the new-look magazine has been fantastic. Over the past six months, we have attracted a number of new advertisers illustrating that they are hungry for innovation."
Emap's overhaul of Bliss began in January with a new logo. As well as shrinking its format to A5, following the lead of Conde Nast's Glamour, Bliss also boosted its celebrity content.
