Size was born as Hans Seisveld in 1981 in Leiden, The Netherlands. He’s still based here, and is a key figure in it’s small, but thriving techno scene.

Music has always been a very important element in his life. He started to play the guitar in the early nineties and soon started to explore more music styles. In 1995 he got in touch with techno music, visiting lots of events and refining his electronic taste. Three years later, he started playing his first records, a habit he hasn’t kicked since. His passionate skills brought him to play at events like Awakenings, Voltt, Timewarp, Teqnology, Legalize, Integrate, Decompression, Monocult, A.S.S., mnml.nl and many more.

Throughout the years he has evolved his own style. It can be described as a mixture of groovy techno, minimal house. Size likes to explore and cross musical borders and combine different styles in the mix. He started off being known for his energetic techno style, but he only plays that on demand now, preferring the broader spectrum now found in his record bags. He knows like no other how to build up the tension in his sets and please the audience with some tight mixing skills.

His love for the music doesn’t stop with spinning records alone. After finishing a sound engineering course in Amsterdam in 2002, production is the next thing on his agenda. With some tracks already finished and lots of projects running, he’s released a stunning release at Truesoul Records and 100% Pure records in 2009. Those releases got huge support from Sven Vath, Dubfire, Adam Beyer, Bart Skils, 2000 and one…

The 17th of April 2009 Size won the 1st price of “De grote prijs van Zuid-Holland” of the category “Dance and producers”. Besides of that he also won the first price voted by the audience. He’s made it into the semi finals of “De grote prijs van Nederland”.
