In your material, you should connect a textureCoodinate node to the UV slot of your texture.
While selecting the texCoord node, you’ll see in the detail panel a line called U tiling and V tilling.
By setting these value greater than 1, you will tile your texture and it will appear smaller.
By setting them under 1, you will “scale” your texture up.
in your case, you should try value around 0.5 / 0.6 maybe 0.7…
Be aware that you can squich your text by setting different value in these 2 box. If you want to keep it square, put the same value in U and V
