Can someone tell me how to change the sizes of input fields in my lightning component, I am using layout and layout item to get them centered on the screen, but I would like both columns to look more uniform.  Also how would I get fields like Description to show more than one line like it does in the OOB Account creation screen? 

Here is the code I have so thus far:

<aura:component implements="force:appHostable,flexipage:availableForAllPageTypes,flexipage:availableForRecordHome,force:hasRecordId,forceCommunity:availableForAllPageTypes,force:lightningQuickAction" access="global" >
    
    <aura:attribute name="PageHeading" type="String" default="New Property Space"/>
    <aura:attribute name="PropertySpaceName" type="String"/>
    <aura:attribute name="SpaceStatus" type="String[]" default="--None--,Vacant, Occupied, Pending"/>
    <aura:attribute name="Property" type="String"/>
    <aura:attribute name="SquareFootage" type="Integer"/>
    <aura:attribute name="DesiredTenantNotes" type="Integer"/>
    <aura:attribute name="PreviousIndustry" type="String[]" default="--None--, TBD"/>
    <aura:attribute name="Tenant" type="String"/>
    <aura:attribute name="LeaseEffectiveDate" type="Date"/>
    <aura:attribute name="LeaseOpportunity" type="String"/>
    <aura:attribute name="LeaseExpirationDate" type="Date"/>
    <aura:attribute name="PropForm" type="PropertySpace__c" default="{'sobjectType': 'PropertySpace__c'}" />

    </lightning:layout>    
        
    </div>    
    
</aura:component> 

Here is a screenshot of the non-uniformity I am talking about:



Thank you in advance for any help provided!
