The 18-year-old, preparing for the doubles event at the London 2012 Olympic Games, is confident that home hopes will benefit when Wimbledon starts a week later from 2015.
Robson, who teams up with Heather Watson at Wimbledon next week, says players will be able to fit in an extra grass tournament following the completion of the French Open, which is played on clay.
"I think it is a great idea, it gives everyone the opportunity to play one more grass tournament which is great," said the former Wimbledon junior champion.
"We play for months on clay and on hard courts and then we only have a three-week grass period, and it's great we now have a four-week grass period.
"For us (British players) we all love playing on grass so we are all really, really happy with the decision.
"It can only help us as we have all always been familiar on grass throughout our careers."
Robson goes into the Games following her best ever performance on the WTA Main Tour last week, as she reached the semi-final of the Italiacom Open in Palermo.
"I have been on clay for the last two weeks so it is going to be a bit of a difference moving back on to grass," said the new British number two.
"I made the semi-final in Palermo which is the best I have ever done at a WTA, and Heather's over in America doing really well and she won in the doubles in Stanford.
"We are both playing really well and are both confident going into the Games."
