Page Layout ⇒ Less Space between equations and text

[eggmanneo]

I'm trying to reduce the space between my text and equations. I mainly use the align environment. I tried using the commands

Code: Select all

\setlength\abovedisplayskip{0pt}
\setlength\belowdisplayskip{0pt}

In the preamble of my document, but these commands didn't seem to change anything. Below is an outline of my code

Code: Select all

\documentclass[12pt]{article}
\usepackage{setspace}
\usepackage{lmodern}
\usepackage{amsmath}
\usepackage{amsfonts}
\usepackage{hyperref}
\usepackage[hmargin=1in,vmargin=1in]{geometry}
\doublespacing
\usepackage{times}
\setlength\abovedisplayskip{0pt}
\setlength\belowdisplayskip{0pt}
\DeclareMathOperator* {\Max}{max}  %in equation mode, this lets you write max wrt choice variables
\usepackage{graphicx}
\def\inputGnumericTable{}  %spreadsheet program I use to make tables for latex
       \usepackage[latin1]{inputenc}
	\usepackage{color}
       \usepackage{array}
	\usepackage{longtable}
       \usepackage{calc}
       \usepackage{multirow}
       \usepackage{hhline}
       \usepackage{ifthen}

\usepackage{harvard}

\begin{document}

\begin{align} \label{eq:budget}
C_t \leq W_{K,m,t}H_{K,m,t}+W_{K,f,t}H_{K,f,t}+T_{m,t}B_{m,t}+T_{f,t}B_{f,t}+Y_t.
\end{align}

the \vspace command seemed to work, but I would have to do this for every equation, and sometimes it can be hard to get the spacing exactly right with this command

Hi,

\normalsize resets those values, that's why they don't have effect in the preamble. A quick way to force the lengths at the beginning of the document:

Code: Select all

\AtBeginDocument{%
  \setlength\abovedisplayskip{0pt}
  \setlength\belowdisplayskip{0pt}}

Or redefine \normalsize, such as for article with base font size 12pt:

Code: Select all

\renewcommand\normalsize{%
   \@setfontsize\normalsize\@xiipt{14.5}%
   \setlength{\abovedisplayskip}{0pt}
   \setlength{\abovedisplayshortskip}{0pt}
   \setlength{\belowdisplayskip}{0pt}
   \setlength{\belowdisplayshortskip}{0pt}
   \let\@listi\@listI}
\makeatother

Or if you don't know that macro or the base font size, you could add to \normalsize:

Code: Select all

\makeatletter
\g@addto@macro{\normalsize}{%
   \setlength{\abovedisplayskip}{0pt}
   \setlength{\abovedisplayshortskip}{0pt}
   \setlength{\belowdisplayskip}{0pt}
   \setlength{\belowdisplayshortskip}{0pt}}
\makeatother

This works, thanks!
