My frame is too big for the limits margins, How do I add more space. to have all my content complete in my presentation. This is the code

    \frac{-\hbar^2}{2m}\bigg( \frac{\partial^2}{\partial x^2}+\frac{\partial^2}{\partial y^2}+\frac{\partial^2}             {\partial z^2}\bigg)\psi(x,y,z)+V(x,y,z)\psi(x,y,z) = E\psi(x,y,z)\label{ecu-gen}

    Donde $\hbar$ es la constante de planck, $m$ es la masa del electrón, $V$ es el Potencial aplicado sobre la red cristalina, $E$ es la energia total del electron.\par\medskip   
Por teorema de Block la solucion de esta ecuación es de la forma.

    \[\psi (x,y,z)=e^{i\bf{k \cdot r}}u_{\bf{k}}(x,y,z)
Donde $r$ es la posicion en la red, $\psi$ es la funcion de onda, $u$ es una funcion periodica con la misma periodicidad del cristal, $\bf{k}$ es llamado el ''Vector Onda del Cristal', $e$ es el numero de Euler e $i$es la unidad imaginaria.\par\medskip

En otras palabras es la multiplicacion de una onda plana por una funcion periodica.

    I think you have to ask the question backwards I have too much content for the frame, how can I reduce it?

  • You may add the optional [shrink] option to yours \frame commands. Commented Dec 1, 2014 at 14:20
  • @percusse I have the same problem with the width margins, and here recommended me aspectratio=169, so i suppose both election are well doned, adding space to the margins and reducing content.

Not an answer but a comment with images:

I'm not sure to understand the problem. If I replace your images (which I don't know where to find them neither their size) with example-images from mwe package I obtain two slides with everything inside. So, what's what doesn't fit? where?

  • You are right @Ignasi I have made the correponding correction to the code, Now have appeared the contend outside the margins. Im able to receive your help.

    @JuanMuñoz: Some suggestions: First, please read Guidelines for Creating Presentations (chapter 5 from beamerusedguide). Second, change beamertheme and select someone which doesn't take so much space with sections on top of frames. Third don't try to write so many things in each slide (which it's related with first suggestion). Who has to read them? If it's a presentation you will explain everything and people will listen you. If listeners have to read what's on every slide, they become readers and don't need a presenter (you)
