The first 24/7 London was published in January with a fortnightly 32,000 print run at 32pp, but the paper has plans to grow to an 80,000 weekly at 36pp by March.
Its current print slot at Bristol Northcliffe Press is not under contract and 24/7 London creative director Steve Boyce said plans to raise the paper's size could knock them off the site's "notoriously busy" Wednesday print slot.
The full-colour tabloid, on 55gsm newsprint, is distributed at tube stations and nightclubs and is handed out around the city.
The paper's distribution has already gone from 32,000 to 50,000 in three issues, but managing director Antony Nutley said the printing might have to move to another site.
"The Wednesday print slot is a pain apparently," he said.
<i>24/7</i> London to up circulation
A new free paper dedicated to the alternative side of London, including the adult entertainment scene, is beginning to outgrow its print slot at Northcliffes Bristol site.
