The marriage between Margaret and Gustaf Adolf is described as a happy love match.
Gustaf Adolf felt great pressure from the "Prussian" military discipline with which he had been raised by his mother, and he was greatly affected by and attracted to Margaret's differing English customs.
The visiting Infanta Eulalia of Spain wrote that the Crown Princess gave the Swedish court "just a touch of the elegance of the Court of St James's" and of how much Margaret loved her life in Sweden.

After her arrival in Sweden, Margaret, who in Sweden was called "Margareta", received lessons in the Swedish language, and asked to be educated in Swedish history and social welfare.
After two years, she spoke good Swedish.
She was also eager to find out more about Sweden, and on many occasions went on incognito trips.
During her first years in Sweden, Margaret behaved with great seriousness and was therefore regarded as stiff, but the view of her changed because of her great interest in sports, where she showed a more relaxed and natural manner.
Margaret took a great interest in many forms of sports; she used the winters for skiing, ice skating and playing hockey (what is nowadays called bandy), and played tennis and golf during the summers.
She also corresponded with various relatives.

Margaret was also interested in art, and was an admirer of the works of Claude Monet.
She photographed, painted, and took a great interest in gardening.
She and her spouse received Sofiero Palace as a wedding gift, and they spent their summers there and made a great effort creating gardens in an English style on the estate; her children participated in their improvement.
In 1915, Margaret as Kronprinsessan Margareta published the book Vår trädgård på Sofiero ("Our Garden at Sofiero") and two years later also Från blomstergården ("From the Flower Garden") illustrated with her own drawings and photographs, which were sold for the benefit of household schools with childcare.

During World War I, Margaret created a sewing society in Sweden to support the Red Cross.
The society was called Kronprinsessans Centralförråd för landstormsmäns beklädnad och utrustning ("The Crown Princess's central storage for clothing and equipment of the home guard"), which was to equip the Swedish armed forces with suitable underwear.
When paraffin supplies ran low she organized a candle collection, and in November 1917 she instituted a scheme to train girls to work on the land.
She also acted as intermediary for relatives separated by the war.
With her help, private letters and requests to trace men missing in action were passed on.
She was also active in her work on behalf of prisoners.
She aided prisoners of war in camps around Europe, especially British nationals.
Margaret's efforts during the war were pro-British, in contrast to her mother-in-law's strictly pro-German attitude.
In 1917, Margaret organized Margaretainsamlingen för de fattiga ("The Margaret fundraiser for the poor").
At the end of the war, when the final steps towards full democracy were taken in Sweden, Margaret's positive attitude to reform influenced her husband the Crown Prince.
Unlike the attitude of her reform-hostile in-laws, King Gustaf and Queen Victoria, this is believed to have eased political tensions and preserved the Swedish monarchy.
