A press arrangement and method for pressing a fibrous web include a main press with extended press nip having a length of at least 150 mm. The main press is configured such that, when operated with a line load LL of at least 1,200 kN/m, a line-load ratio LLR of at least 0.69 and at most 1.52 is obtained. The line-load ratio LLR is defined as the quotient of a weighted line load WLL to the line load LL, the weighted line load WLL being the result of integration of the squared local pressure p(x)2, weighted with a weighting factor A, over the nip length x, the weighting factor A being one divided by ten megapascal. The line load LL is the result of integration of the local pressure p(x) over the nip length x, such that the following formula for the line-load ratio LLR applies: LLR = WLL LL = ∫ A * p ( x ) 2 dx ∫ p ( x ) dx = ∫ 1 10 MPa * p ( x ) 2 d x ∫ p ( x ) d x
