'Size Matters' was the subject set by Beatrix Ruf, director of the Stedeljik Museum in Amsterdam, for the inaugural session of Verbier Art Summit in 2016. Slyce lectured in response to Ruf's account of the inflationary forces driving public institutions in response to growing audiences. His talk aimed to bring the topic closer to the production of artists and explore how 'size' can obscure and collapse a central concern within artists' practices regarding 'scale': "Size determines the work; scale determines the art." Robert Smithson.

Verbier Art Summit is positioned as a 'Davos of the art world' and aims to create an international platform "for high-level dialogue by bringing together influential art world stakeholders that are looking to have a real impact on the art world."

In January 2017 the Verbier Art Summit took place across four days with a focus on 'Size Matters!'. Invited speakers included Beatrix Ruf, Rem Koolhaas, Tino Sehgal, Tobias Madison, Mark Fisher, Cissie Fu, Constantijn van Orange, and Christoper Kulendran Thomas.

The 2017 Summit is captured and extended in a publication edited by Slyce and SMA and jointly published by SMA, Walter Koenig and Verbier Art Summit. Slyce contributes an essay as well as editing the publication. Content includes essays by Rem Koolhaas, Tino Sehgal, and Prince Constantijn van Oranje. Additional essays in the edited volume will come from Sir Nicholas Serota, Benjamin Bratton, Cissie Fu, Dave Beech, Daniel Birnbaum and Tobias Madison.
