Hi, for nice linebreaking we can adjust math formulas by the use of NC, NR alignment. But if someone only wants long formulas to fit in a defined area, and want them to break automatically ... is there a handy solution? (Below are examples that don't work) Thanks, Steffen ------- \starttext \placeformula \startformula[9pt] I=\big\{\lambda u(x_0-\pi^H K)+(1-\lambda)[\pi^L u(x_0-K+(1-\pi^L)Z_{L'}) +(1-\pi^L)u(x_0-\pi^L Z_{L'})]\big\}-\big\{\pi^U u(x_0-K+(1-\pi^U)Z_{U'}) +(1-\pi^U)u(x_0-\pi^U Z_{U'})\big\}. \stopformula \defineframedtext [defbackground] [width=10cm, frame=on, location=paragraph] \startdefbackground \placeformula \startformula[9pt] I=\big\{\lambda u(x_0-\pi^H K)+(1-\lambda)[\pi^L u(x_0-K+(1-\pi^L)Z_{L'}) +(1-\pi^L)u(x_0-\pi^L Z_{L'})]\big\} -\big\{\pi^U u(x_0-K+(1-\pi^U)Z_{U'}) +(1-\pi^U)u(x_0-\pi^U Z_{U'})\big\}. \stopformula \stopdefbackground \definelayer[mylayer] \setlayerframed [mylayer] [x=25mm, y=85mm, height=43.5mm, width=10cm,align=block] { \placeformula \startformula[9pt] I=\big\{\lambda u(x_0-\pi^H K)+(1-\lambda)[\pi^L u(x_0-K+(1-\pi^L)Z_{L'}) +(1-\pi^L)u(x_0-\pi^L Z_{L'})]\big\} -\big\{\pi^U u(x_0-K+(1-\pi^U)Z_{U'}) +(1-\pi^U)u(x_0-\pi^U Z_{U'})\big\}. \stopformula } \setupbackgrounds[page][background=mylayer] \stoptext
