We show that every (possibly unbounded) convex polygonPinwithmedges can be represented by inequalitiesp1≥ 0, . . .,pn≥ 0, where thepi’s are products of at mostkaffine functions each vanishing on an edge ofPandn=n(m,k) satisfieswiths(m,k) ≔ max {m/k, log2m} andas. This choice ofnis asymptotically best possible. An analogous result on representing the interior ofPin the formp1> 0, . . .,pn> 0 is also given. Fork≤m/log2mthese statements remain valid for representations with arbitrary polynomials of degree not exceedingk.
