[?] Increase the size of a legend in LisDensityPlot?

Questions

How can I increase legend size in ListDensityPlot? I tried that by using LegendSize, but it doesn’t work in Mathematica 10.
Thanks.

Without some example code, what you actually tried it is hard to answer where it went wrong. On my machine on Mathematica 9, the following works:

ListDensityPlot[
 Table[Sin[j^2 + i], {i, 0, Pi, 0.02}, {j, 0, Pi, 0.02}],
 PlotLegends -> 
  Placed[BarLegend[Automatic, LegendMarkerSize -> 500], Right]
]

Thank you for your help. I meant increasing the size of font of legend.
By the way, I solved by using this:

PlotLegends -> BarLegend[Automatic, LabelStyle -> {FontSize -> 15}]

Exactly. I wasn’t really sure what you exactly wanted to enlarge but it was my hope that you see that you can adjust different things of legend by packing it in the PlotLegends option.
