Keterangan

Jika Anda mengukur margin dalam milimeter, kalikan lebar margin yang Anda inginkan dalam milimeter dengan 3,937 untuk menentukan pengukuran yang benar dalam seratus inci. Misalnya, jika Anda menginginkan margin 25mm, kalikan dengan 3,937 dan hasilnya adalah 98 saat dibulatkan ke bawah. Anda kemudian akan menetapkan anggota yang sesuai Margins ke 98.
