Zakat al-Fitr entails providing for a full meal for the day of Eid. As the standards vary from country to country, one should follow the rule set by the scholars in every country.
So, it would be best if you considered the ruling of the eminent scholars of Bangladesh in observing this essential religious duty.
You should know that since you are part of the community of believers, you should not do so individually according to your desire or opinion.
Having said this, however, let me also point out another advice of Imam Ibn Taymiyyah: “while following the standard of the country, it is still better to offer more than the standard especially if one is well to do and can afford to do so, for even as he would be celebrating.”
Almighty Allah knows best.
