Yes, the size of a capacitor "matters" just as much as the size of a resistor "matters". In both a capacitor and a resistor "size" refers not only to the electrical value of the item but to its current-carrying capacity: a small resistor will burn up if you try to push too much current through it. A big resistor will be able to carry a much higher current than a small one having the same resistance value.
Similarly, a small capacitor will be destroyed if you try to push too much current through it and a big capacitor will be able to carry a much higher current than a small one, even if both have exactly the same capacitance value. Capacitance values are measured in Farads (F), microFarads (uF) and picoFarads (pF). Just as a resistor has "Resistance " measured in Ohms, a capacitor has "Capacitive Reactance" or "Impedance", measured in Ohms.
The Impedance of a capacitor varies with the frequency of the alternating current passing through it. (This is quite different behavior to a resistor: the Resistance of a resistor does not change with the frequency.) If you look in a book about electrical engineering components you will be able to learn how the Capacitive Impedance is calculated according to the frequency. "The impedance of a capacitor is inversely proportional to the frequency - that is, for very high-frequency alternating currents the reactance approaches zero - so that a capacitor is nearly a short circuit to a very high frequency AC source. Conversely, for very low frequency alternating currents, the reactance increases without bound so that a capacitor is nearly an open circuit to a very low frequency AC source. This frequency-dependent behaviour accounts for most uses of the capacitor." [From Answers.com]

How does the size of an electrolyte capacitor vary with its capacitance value?
A: Capacitance vary directly with the area applied the bigger the area the bigger the capacitor. There is another element that will increase the size that is the rating of the capacitor voltage since more material will have to be used to insulate the plates
Can a non polarized capacitor be connected to a direct current circuit?
Yes, you can connect a polarized capacitor to a direct current. Make sure you get your polarization is correct.A non polarized capacitor can be connected in a DC circuit as well. "Non Polarized" just means it does not matter which side of the capacitor is positive. If you attempt to connect a polarized capacitor in a DC circuit backwards, you will know when the capacitor explodes.
What is on the model number of a HVAC compressor to tell what size capacitor in needed?
3100y20q800cl
What size capacitor you need for a 1000 watts amplifier?
It takes 1 farad for every 1000 watts so u need 2 farads.
What happens when start capacitor is slightly over sized?
C=QV it doesnt depend on size.
Can we use AC capacitor in surge suppression circuit DC?
A capacitor is a capacitor, no matter what circuits you use it in. There is no difference between one used in AC and one in DC, except perhaps the size that is appropriate.
How do i size up a start capacitor?
Read the capacitor that you remove
What size capacitor?
Capacitors come in various sizes, your question is to non specific (capacitor for WHAT) for a detailed answer.

What is the net force of a capacitor?
This question does not make sense. For what use, or what kind, even the size are all factors of a capacitor. Look up the definition of what a capacitor is and then ask a real question.
How a capacitor steps down ac?
A capacitor doesn't step down AC voltage, that's what a transformer does! It really can't, no matter what the circumstances.
What size Capacitor is need for copeland cr38k6pfv875?
35mfd/440V
What is the difference between capacitor and capacitance?
A capacitor is a device that stores an electrical charge, or if you prefer- resists any change in voltage applied to it. Capacitance is a measure of the size or ability of a capacitor to do that. This is the Farad
What are the Darwbacks of non-polar capacitor over polar capacitor?
A: Polarized capacitors can be smaller in size as compared to a non polarized in the same capacity
