The New York Times Company has also redesigned the print edition of the IHT, which now features clearer headings, improved page navigation, more anchored positions, better designed briefs columns and pointers to web articles, and greater emphasis on photography.
Typographically, the IHT has also introduced a new Cheltenham typeface and a cleaner nameplate that gives "international" more prominence.
Martin Gottlieb, editor of global edition, said: "Redesigning the newspaper and reconfiguring our global online presence at the same time created significant opportunities for us journalistically:
"By consolidating web operations and improving design processes, we are freeing up editorial energies to focus on delivering the accurate reporting, thought-provoking writing and sharp analysis that our international readers need now more than ever."
In the new design, the IHT's business section, which is produced in collaboration with Reuters, is given added prominence by being anchored at the back of the newspaper Monday through Friday.
Stephen Dunbar-Johnson, publisher of the IHT, said: "Together with The New York Times, we are creating a powerhouse for high quality global news -- it is thanks to closer integration with New York that has made the dynamic new Global Edition online a round-the-clock reality, and it is thanks to this that we have such a clear and sparkling new design for our newspaper.
"Today the IHT is demonstrating its steadfast commitment to steering its international readers through the momentous events of a fast changing world, serving readers and advertisers with creativity and vision."
