# Removing one blank page between two chapters

How can I remove one of the blank page between two chapters.

``````     \documentclass[12pt,titlepage,a4paper]{book}

\input{chapter1}
\newcommand*\NewPage{\clearpage\thispagestyle{empty}\null}
\NewPage
\input{chapter2}
``````
• What is the `document class (+ options)`? Do you have any layout package loaded? How many blank pages do you have between chapters? – Bernard Jul 23 '14 at 12:28
• what is the intention of the `\NewPage` command (which looks wrong) Please always provide a complete small document that shows the problem. – David Carlisle Jul 23 '14 at 12:33
• The document class is : \documentclass[12pt,titlepage,a4paper]{book}, In this way that I create new command I have two blank pages. – rose Jul 23 '14 at 12:34
• Of course you get two, because of `\null` that makes the current page non empty; but you don't need `\NewPage`, because `\chapter` issues `\cleardoublepage`, so the beginning of `chapter2.tex` will already insert a blank page if needed, and just one. – egreg Jul 23 '14 at 12:41

`````` \newcommand*\NewPage{\clearpage\thispagestyle{empty}\null}
Should have the desired effect (the definition leaving `\null` at the top of the following page seems to be incorrect in all cases, and certainly is not wanted before a chapter heading)
If you are using a big table inside the page then you most probably get a blank space before the table start. Use `longtable` instead of `tabular` or `table` environment.
